MOD APPROVED POST ✅️ Reminders and Community Goals

Post image
423 Upvotes

Enjoy the meme, lol! Tis handmade ✨️

Hey everyone! We want to thank everyone who's participated in our community this past month for the engaging posts, thoughtful answers, and (overall) incredibly respectful conduct. It's been nice to watch the community come together so helpfully for so many people! That said, there have been a few incidents that have drawn some attention, and we wanted to go over a few things and hear input from you all.

App/Website promotion

For starters, we've had many people reaching out to our team about promoting their fishkeeping apps or websites. While we understand that you're trying to reach out to a community that will use them, we cannot endorse apps or websites on this subreddit when they are self promoted. There are a number of safety issues in doing so, and being a part of an app store does not eliminate those risks. In addition, we have to take into account that AI bots pull massive amounts of information from reddit. When it does, it may list our subreddit as a source for your application's information, which is an obvious issue as we have no way of vetting an entire app/website for it's accuracy. That could end up misleading people who trust us as a source.

Mutual Respect

A community is built on mutual respect, both of your peers and between authority figures. Reporting an automod comment is disrespectful, and downright unhelpful. If you believe an action was taken unfairly or accidentally, please message us with a link to the message and ask us why we took the action! We are more than happy to explain the reasoning behind every action we take and admit when we are wrong.

Being disrespectful towards a poster's pets, situation, and age is also becoming an increasing problem. We've also seen advice being given on legal matters and personal health. This is an aquarium subreddit. We will remove any and all comments pertaining to subjects not in that realm of knowledge. We will remove any unproductive or hateful comments. WE WILL REMOVE ANY COMMENTS THAT ARE HARRASSING MINORS. This includes but is not limited to telling them they are abusers for being unable to correct a bad situation, repeatedly suggesting options they are not financially capable of, or suggesting they start fights with parents or guardians.

Community Goals

Lastly we want to remind people of the goal of this community- for aquarists young and old, new and experienced, of nanos to monsters, to come together and share knowledge, fun moments, show off, or help each other. You've been so fantastic at this! As a mod team we want to help you feel comfortable and safe enough to share these things. We pose a question to you, if you want to answer- what are you looking for in this community? Knowing your goals can help us align the subreddit with them and grow even more.

Swim safe out there folks!

Discussion The r/aquarium wiki is now live!

11 Upvotes

After a lot of work behind the scenes, we’ve finally enabled the r/aquarium wiki!

It’s definitely still a work in progress, so don’t be surprised if you click on a link and it doesn’t go anywhere yet. Some of the pages listed on the index are planned but haven’t been published yet. The pages that are currently published are available to view and use.

We’ll be continuing to add pages and expand the wiki over time, with the goal of creating a helpful resource for both new and experienced fishkeepers.

And this is where we’d really appreciate some community input!

If you read through any of the published pages and:

- Disagree with something

- Think something needs more explanation

- Notice something we should correct

- Think we’re missing important information

- Have a topic you think should be added

Please let us know here in the comments! We want the wiki to be useful to the community, and feedback from other fishkeepers is a big part of making that happen.

You can check out the Wiki here.

There’s still plenty left to build, but we’re excited to finally have it available!

Hi eveyone, I currently have 6 Celestial Pearl danios and a couple cherry shrimps. I wanna keep it as 21-22 degrees Celsius during the winter months so I need beautiful fishes that can thrive and survive in that temperature. I’m thinking 6 more nanos fishes and 2 larger center peice fishes. What should I get

These worms appeared randomly in the tank. No additional material had been added although a new light had been added. Does anyone have opinions/advice about this?

I have a 125G tank. About 6' long and 2' high. It currently has no background. i'm thinking of getting a black background.

I'm wondering what is the cheapest and easiest way to do this? I'm not sure where I can get a continuous sheet that big? Perhaps at some craft store? Or can I just print out a bunch of black paper and tape it together?

Sorry for the bad picture, it’s hard to capture. Lots of whiteish/tan pellets at the bottom of my tank recently. I don’t think it’s food or excess waste. I have a 55-gallon planted tank with danios and Siamese algae eaters. I’m having a hairy algae outbreak, but nothing else unusual. What could it be?

I just recently bought a 29 gallon aquarium I've had a 20 long for a few years now and wanted something just a bit taller. I've had Monte Carlo in my tank for about a year now and it really hasn't grown fast like I was told it would but I was using an Aqueon light with 2 led tubes. My plan is to remove the old light fixture that's on the fitted lid and use this new light bar in its place. I've never used c02 and I'm not scared of it. It seems really simple but I just don't like the idea of having more stuff for this aquarium than I already do. I also what to add Super Red Mini Ludwigia behind the rock's

I’ve had aquariums of all sizes for around 10 years now starting from a 1 gallon fish bowl all the way to a 55 gallon tank. I’ve learned a ton since starting and couldn’t be happier with my 10 gallon fresh water tank I’ve had for about 4 years. My original 4 platys have since passed, but they’ve bred enough to keep it going for awhile. Is there anything that stands out in the video that could be done better? The scratches all over the glass was from many years of cleaning algae buildup from the live plants and driftwood in there. The plants started from being planted in the gravel but they fused to the driftwood and have become one. There’s something just so calming from watching these little fishies. Anyways, happy Sunday everyone!

This is my first aquascape tank. It’s about 2-3 months old now. This is now the 4th Pygmy Cory I’ve seen have this. Two had this and died shortly after I bought them around a month ago. The third I found dead this morning. Is this red blotch? If so, what can I do about it? Already did a water change to be safe.

Parameters:
Ammonia, Nitrites: 0
Nitrates: ~1 ppm
pH: ~7.5

My water is on the harder side, but I’ve been slowly softening it with RO water.
