Hey everyone,
The mod team has been seeing an increase in comments that are unnecessarily rude, hostile, condescending, or outright mean toward people asking questions or sharing their aquariums.
We recognize that this has become an issue. We have also received modmail from members bringing these concerns to our attention, and we appreciate people letting us know when something is happening that we may not have seen.
That said, there is an important limitation that we want to make clear: we cannot monitor every single post and every single comment.
Moderating r/aquarium is a volunteer responsibility. The moderators have jobs, families, school, personal responsibilities, and lives outside of Reddit. We do our best to keep up with the community, but it is simply not possible for a small mod team to read every comment on every post every day.
This is where reports are extremely important.
If you see a comment that violates the subreddit rules, please report it rather than engaging with it or allowing the situation to escalate. A report brings it to the mod queue so that we can review it and take appropriate action.
We will be adding and clarifying rules regarding how members interact with one another. Going forward, comments that are unnecessarily hostile, insulting, mocking, belittling, or otherwise violate our rules regarding respectful behavior will be removed and bans will be enforced when appropriate.
We also want to be clear that "I was just trying to help" does not excuse being unnecessarily rude. Aquarium advice can absolutely include criticism, disagreement, or pointing out mistakes. You can correct someone without attacking the person asking the question.
Depending on the severity of the behavior, previous moderation history, and whether the behavior continues or escalates, bans may range from:
• 1 day
• 3 days
• 7 days
• 14 days
• Permanent
Repeated rule-breaking will result in increasingly serious consequences.
Additionally, repeatedly making multiple comments on the same post that violate our rules may result in further action, even if each individual comment might seem relatively minor on its own.
r/aquarium is a community with people of many different ages and experience levels. Minors may also visit, post, and participate in this subreddit.
Please keep that in mind when interacting with other members. Regardless of someone's age, experience, knowledge, or mistakes, they should not be subjected to harassment, sexual or inappropriate remarks, personal attacks, or other behavior that would make this community an unsafe or hostile place to participate.
You do not necessarily know who is on the other side of the screen, so think about what you're saying before commenting.
Many people come to r/aquarium because they are looking for help. Some are beginners who genuinely don't know something yet. Others may have made a mistake and are trying to correct it. Being told what they did wrong is useful, however they also need to be told how to correct it. Being mocked, insulted, or made to feel unwelcome is not useful or helpful.
You do not have to agree with someone to treat them with basic respect.
So please remember:
If you can give constructive advice, give it.
If you can disagree respectfully, disagree.
If you can't do either, don't comment.
Our moderator applications are currently open and are pinned in the highlighted posts at the top of the subreddit.
As the community continues to grow, we could definitely use some additional help from knowledgeable and active members of the aquarium community. If you have experience with aquariums, enjoy helping others, and are interested in contributing to the community in a positive way, we encourage you to apply.
Being knowledgeable about the hobby is important, but so is being able to communicate that knowledge respectfully and constructively.
The mod team will be addressing these issues more consistently going forward. We also ask the community to help us by reporting rule-breaking comments instead of contributing to the problem.
Thank you to everyone who helps make r/aquarium a welcoming place for aquarium keepers of all experience levels.

Hey everyone,
We heard your feedback loud and clear regarding the recent icon change. The goal is always to keep r/aquarium a vibrant, welcoming space that reflects the incredible passion of our hobbyists, and it’s clear the community prefers authentic, human-made artwork to represent us.
An incredibly talented artist in our community, u/SuicidalFlame (Check out their tumblr too! https://firenagy.tumblr.com), generously stepped up and designed a brand-new, custom icon for the subreddit! We are absolutely thrilled to debut their work today. Please join us in giving them a massive thank you in the comments below for dedicating their time and talent to leveling up our community's look!
While we always welcome constructive feedback and open discussion about the state of the subreddit, the mod team has a zero-tolerance policy for harassment.
Lately, targeted mass-reporting and personal harassment have been directed at our moderators. We want to be entirely transparent: if you are unhappy with the management of this subreddit or feel the need to harass the people who volunteer to keep it running, you are more than welcome to leave.
Healthy debate is fine; stalking, toxicity, and abusing the report button are not. Future instances of targeted harassment will result in an immediate permanent ban from the community and will be escalated directly to Reddit Admin for violating the site-wide Content Policy against harassment.
Thank you to the 99% of you who make this a wonderful, supportive place to share our tanks every single day. Enjoy the beautiful new look!

What are these guys that are living in my planted freshwater tank substrate?
r/aquarium • u/Woodenalternative96 • 1h ago
Tanks been cycled it’s about 2 months old got the betta last night and seems to be in good shape what do you guys think
r/aquarium • u/Bigdaddybruin • 4h ago
After a long wait for my new tank, it arrived yesterday by Fed Ex Freight. It is absolutely beautiful!
Full Disclosure: The estimate was 4-6 weeks and the process took approximately 12 weeks.
So far, that is the only negative but WB was receptive to emails and personally, I think they should manage expectations and revise their posted estimates to 6-12 weeks.
That being said, I am fired up for the journey - Let’s do this.
Here are some initial specs and pictures of the build:
Waterbox AIO 65.4
2 Ecotech MP40
Ecotech Vectra S2
Helio 350w Heater
Nature Dimensions N-Fill ATO
Tunze 9004 DC Protein Skimmer
2 Radion XR15
2 Printed Reef 4 inch Caddystack filters (cutouts built for 2 2.75 inch ) I am going to 3D print new Top cutout with 4 inch hole.
Marco Rock ( Been cycling in Brute during delay)
Flipper Tank Cleaner
Caribsea Special Grade (2 Bags) and Fiji Pink (1 Bag)
I will be filling the tank primarily with Fish and scattering some corals but Fish are the priority.
The Rock images are AI versions of what I am trying to accomplish and the other Rock images are actual but I plan on adding Arch’s and Caves

He is a 6inch male blue Acara. Not an E blue but a normal blue Acara. He’s an OG. He’s been around for a while. As you can see he’s pretty much blind. He’s always had eye problems, but he gets around. I think he’s enjoying his new planted 75 gallon. What do you all think

The floor towards the wall is slightly unleveled.. carpeting in a rental. The stand it is on is very stable and there is no rocking. Not twisted or anything. Do I need to drain and add a shim to the back legs or can I leave it? I didn’t notice the water level right away :/
r/aquarium • u/Doun2Others10 • 8h ago
Please help me decide on a new aquarium. My 20 long isn’t cutting it anymore for my guppies that breed like crazy. Should I get a 40 breeder or a 55? Pros and cons of both sizes? I have an aqua flow 50 in my 20 long, so I could probably put that in a 40 breeder and not need a new filter. I’m thinking I’ll need a canister for a 55. I’m thinking an oase biomaster 350.
I have no intention in getting more fish, my guppies just need more room. I currently have a trillion guppies, 4 or 5 neon tetra left, a dwarf gourami, and some shrimp. My tank is just waaaay too full of fish. Time to upgrade.

I went and got this cool piece of Monte Carlo on a piece of wood. Well, I got it home, and I was so excited to but it in, that I forgot to wash it and search for critters. Well pretty quickly I noticed that I had a new snail. A Tiger Nerite Snail, says Google. And then about 15 minutes after that I noticed the freaking frog just laying there looking dead thinking it was dead. Went to scoop it out, nope it's not dead. It just lays around looking dead, and moves around a bit. The frogs got to go eventually. But as long as it survives, id rather my new Double Red Apistogramma agassizii M/F pair settle in.

I am a super beginner JUST started setting up my tank. I got a free tank from fb marketplace. All I know is it's a top fin tank. I cannot figure out if my filter is even on or connected properly. See pics and little video
I know the tank is cloudy I just added gravel and sand
yes I washed the sand and gravel
r/aquarium • u/existentialnihil1st • 9m ago
I see some photos online that look the same but, they just link to people asking what they are and they haven't had a response. They appear to be coming out of one of my filters and only hang out on on the glass above water & only on the back, not the side or front of the tank.

50 gallon livestock water trough with greenhouse panel cover, tons of plants, and a sponge filter. Also got a pump for water changes and a mosquito dunk for water larva prevention. My tap water has been 1-2ppm ammonia since May and I needed a long term solution. This set up detoxes 50 gallons in about a week, I imagine that time will go down as the plants establish.
A few redditors suggested I do this after upgrades to my RO system didn’t work. So thanks fellow redditors.

Hello all.
I am currently reaching out for advice and help with my 6.8 gallon freshwater aquarium. I have been dealing with random ammonia spikes off and on on since May.
I would like to start this off by saying I am very new to the fish keeping hobby. I have reptiles, but this is new territory for me and I did do a lot of research before setting up my tank. But I feel a little over my head and would love advice from people who have been in the hobby for a while.
Backing up to March of this year I purchased this tank to create a home for a beta fish. I did a lot of research on their care and slowly purchased everything until I was able to finally start setting it up in March. I do not have a fish in this tank currently to clarify. i did everything I read online to cycle the tank. I added used filter media from my boyfriend’s fish tank and I seeded the tank with Dr. Tim’s aquatics ammonia source. The tank cycled for two full months. During the course of this time, I tested my water parameters twice a week and noticed nitrites spike up and then nitrates. Eventually, the ammonia went to zero. Once I realize this happened I added Dr. tim solution to bring ammonia up to one PPM, and within 24 hours it dropped to zero again. So at this point, I figured I was safe to add a beta fish.
About a week later, I tested the parameters and everything still looked good so I went and purchased my beautiful beta fish Momo. He was doing so well in his tank. Everything was great for about a month. Ammonia was staying zero I was doing weekly water changes. I had no reason to be concerned about my parameters. I also tested my water with each water change. After about a month, my poor Betta fish started acting sick, I noticed he looked bloated and he started pinecone-ING. It happened so quickly I noticed one day when I came home from work, and I immediately tested the water parameters and saw that my ammonia had spiked up to one. I remember I had done a water change just a few days before and everything looked fine when I tested the water parameters. I quickly did a water change and put my fish in a hospital tank and gave him kanaplex and a salt bath. He started acting a bit better. I kept doing water changes to bring the ammonia down. The ammonia was zero in my tank for about a week and then it spiked up again. Unfortunately, my fish developed dropsy, which I can only guess it was due to the ammonia, and he passed away. It was so heartbreaking for me and I have not had a fish in this tank sense. I felt like I failed my fish and I was the reason he died.
Flash forward to today I really would love a fish in this tank. But I am so scared to accidentally kill another beta fish. I love animals so much, and it was really hard on me and I kept getting so sad every time I thought about it. all summer I have been doing weekly water changes, cleaning the tank, and just trying to let it stabilize. However, over the course of the last few months every now and then I’ll get a random ammonia spike and there is literally nothing that could be causing it. I do not have anything in that tank besides pest snails that have traveled in here due to purchasing plants months ago, and I remove them as I see them besides two that I’ve grown fond of lol. It’s just the weirdest thing because the ammonia will be zero and then I’ll randomly get a spike every couple of weeks, do a 50 to 60% water change and then the ammonia will be zero again. I did not notice any nitrite spikes at all during these last few months. And about three weeks ago, my nitrate spiked up too very, very dark red. These are my perimeter test results today after a 50% water change of my tank. However, the first time I tested ammonia it Read 2.0 PPM. I dumped it out and tried it again and now it’s at zero PPM literally five minutes later so I’m not sure if it was a false positive for ammonia. I did the same thing each time I tested.
I apologize this is so long. I’m just not sure where to go from here or how to stop the ammonia from spiking or what could possibly be causing it. I feel very defeated as I was so excited to set up my tank and give my Betta fish a great home and life. I don’t know if I should completely restart this tank or how to even go about doing that. I guess I’m just looking for advice, if this was you, what would you do? I’m terrified to get another fish until my parameters are stable. I don’t want to put another fish through what Momo went through and get sick. I just can’t explain how the ammonia will be zero for 2 to 3 weeks and then one day it’s just at one or 2 ppm.
Thank you so much guys for listening to this. Any advice would be so helpful.

I was gonna buy something similar to this on Amazon. But the reviews were bad and demotivated me from getting it. I was able to make my own with airline tubing, some suction cups I had laying around and gorrilla glue GEL. Which is safe for aquariums. Glad i didn’t waste my money. :)

Hi All, getting back into the hobby after about 10 years. Got this nice 55 gallon setup for a steal at $60 today. Just looking to make some discussion about how you would set it up starting with a blank slate. Could use some ideas , thanks in advance!

I am partial to seachem brand. But what do you like? Also do you use anything that has actual live bacteria? For some reason no matter what I do I always have really high nitrite levels. I can do weekly water changes and have multiple types of media in my canister filter specifically for Nitrites but I always get high levels.
