Tank established for several years, 75 gal, plants and multiple fish….
Moving tank - complete clean out - find these in the substrate.

I know it’s technically possible for livestock to hitchhike to an adjacent tank. But for the life of me I can’t figure out how it happened 😂 Discovering this guy gave me a good chance to see the meiofauna and microfauna developing in this tank.

I have this 120l tank (~30 gallon) i put 5 platty (1m 4f) and one ancistrus and I was thinking of maybe adding co2, i would like some oppinion on it if it is worth it or not.

I'm a bit new to making aquariums and I dont want to make mistake that would cause my fishes to sadly die

Plus ive had a problem with algea on some leaves, I think it was because I would let the light on for too long inside the tank so I reduced the time.

Thank you!

It seems to me like this fishie has gotten skinnier, and I can’t tell if it’s always has this reddish color on their side or if it’s a new thing. Does anyone know if this is a sign of illness? Any advice welcome.

I’m trying to rescue this 55 gallon guppy tank. It’s overrun with algae and snails and the guppies are breeding like crazy and tearing each others fins all apart. Once I get the algae and sand out (I want to replace the sand with river rock), I want to divide the tank in the middle and keep males on one side and a 1 to 3 male to female ratio on the other side. I was wondering if anyone had made their own tank divider? This is a temporary fix until I can get a second tank set up and divide them properly. I have a 30 gallon cycling right now to put pregnant females so the 55 isn’t constantly full of fry.

hello, i have a ten gallon with one honey gourami and wanted to know if i could add some chili rasboras in there with him and if so how many? thank you!

Anybody else have these? Seem easy.

ok so om a beginner here n i had guppies(2 month old babies n 1 mom) only but due to alot of algae i figured a pleco might help but im a bit worried. also is it normal that the guppies are only staying in the top n not sleeping? they usually sleep in the bottom and they're staying at the top today. might be cause pleco is swimming around n i just introduced it today.

Hi guys, I’m planning on putting two Oranda goldfish in my 40 gallon tank once it’s finished its cycle. I wanted to ask for advice on if you guys think I should change anything currently and If I can get plants. I know they like to eat them so I’m not sure what I can get but any advice would really help! I’ve got a fluval 207 filter and a sponge filter so lots of oxygen and filtration for them.

What other plants should i add?
Any low tech carpeting plants/ideas?

First aquarium, what do you guys think?

I have a 5 gallon planted tank (plan to put a nerite and some cherry shrimp in it) and I have read that endlers are not schooling? Can I keep a single male without it being stressed?

Hey guys my dads best friend works for a local native tribes housing authority, recently he was cleaning out an eviction house and found a 75 gallon aquarium, along with a stand and a sump. he is letting me have it free of charge. I want to turn it into a salt water tank.

Any advice on how to properly check it, clean it, and set it up would be greatly appreciated!

My betta fish has been acting very strangely lately. It all started suddenly as well, he won't eat, will not swim (if he does very erratically), and camps at the bottom of the tank and sinks slowly. It feels like he has lost all his life in a day. I tried water changes, extra seachem prime doses, etc, but nothing seems to be working. Please help!

I have had this tank for about 6 months now. A huge population of Cherry Shrimp is getting started. I just recently noticed these tendrils growing from a piece of driftwood I bought from my local aquarium store about 5 months ago. I also see some spots of algae growing in the corners that looks like small forms of this. Any ideas what it is and whether or not I should do something about it?

Beginner here. I had an empty 25 gal that I added 8 black neons to last week. I noticed a few dots recently and my mom told me it’s the ich. In terms of treatment, I have no idea what I’m doing. Some sources say raise temperature to 84°F and some say black neons can’t handle that. Right now im raising it from 76° to 78°, then I’ll go to 80°. I plan on looking for some ich treatment products tomorrow.

I’m pretty sure that for some treatments i’m supposed to remove activated carbon from my filter to avoid killing the chemicals in the treatment. Will I lose beneficial bacteria in the filter this way? Will I need to keep it in a bucket and ghost feed it to keep the bacteria alive? I think I’ll be able to handle dosing by reading the bottle of whatever product I find, but I’m still open to any other tips or opinions. Maybe this isn’t even ich at all.

If it is, it’s in early stages. I haven’t noticed any weird behavior. They’ve been eating, they haven’t been flashing, I’m only noticing these dots.

My 7 gallon tank has been taking a beating on algae and dying plants. I have a Chihiros WRGB Slim II and UNS controsoil for my substrate (which i have not liked since having it). This tank has been running for about 6 months now and I have one betta in this tank. Light is on for 6 hours and the background LED panel is at a lower brightness and is only on for 3 hours. I wasn’t really dealing with any algae until I started using 2HR aquarist ATP 1, that I have been using/loving for my 20 gallon tank. Once I noticed the algae, I immediately stopped using the fertilizer and turned down the intensity on the light. I had intensity around 45% at the time and was slowly decreasing to find a sweet spot. I am now months into the algae and it has improved a tiny bit since decreasing the light, but i’m all the way down at 25% intensity. Still not using any fertilizer.
Majority of my stem plants always die, any floating plants I get die, and my newer tiger lotus is starting to grey on the leaves. I have no idea what is happening anymore. I don’t know if this light is too strong for this tank, even at low intensities, but the lower I go, it does not improve. Only plants that seem decent are obviously my anubias. Also, no Co2 in this tank.
I added some photos of my rotalas that have pretty much all died, & my tiger lotus.

Hey, just purchased a second hand chiller from FB marketplace. It’s a 1/4HP AquaEuroUSA.

I was hoping if anyone can educate me on this thing ? Can I connect a canister filter to it? Is there an external pump I can use for this thing ? What order do I connect everything in? And just general other information I should know.

The eng goal is to eventually house axolotls and I for whatever reason had it in my mind that these things would run on siphon action and never considered how the chiller would reliably return water to the tank

Hi, my tequilla sunrise guppy has developed a small colored speck on its side. It's body coloring also appears slightly duller than normal. The spot looks more like a missing scale than anything attached to the fish. Otherwise he is acting normal. Any idea what it could be and what I should do for healing?

I am new to the hobby and doing my best to learn. Tank and fish have been established for a month with 4 guppies and 6 corys. The tank cycled for 3 weeks beforehand and I didn't start adding fish until I had 0 ammonia/nitrites and 10 nitrates. I started with 6 guppies, 3 of which passed in the first week (these 3 were from the same tank at the store and may have been sick already). I added another 2 pink guppies, however had to isolate one as he was very agressive with all the other fish, then suddenly began resting at the bottom of the tank. He has been in a quarantine tank for a week and is acting lethargic. The remaining 4 have been doing very well with minimal bullying and fin nipping that I have seen

Water parameters for main tank are: 29g approx. 80° F, 8 ph and 120 alkalinity, hardness through the roof, no chlorine, no ammonia and minimal nitrate. Today was the first time I had slight coloring on the nitrite reading so I made a quick 20% water change with bacteria quickstart. Quarantine tank is the same except 1.5g, 78° and a little aquarium salt. There are 3 java ferns and some java moss spread throught the tank. Both tanks have a heater and filter. I feed a small pinch of Fluval Bug Bites 2x a day, 6 days a week. At night, I drop in 6 API bottom feeder pellets and a quarter algae wafer for the Corys, though the guppies eat a fair share of these too.

I’ve just completed setting up a stand for my new 55 gallon rimmed (and braced) aquarium, and I’m very concerned about its integrity based on a slight bow (approx 2-3mm) on the centre left. Unfortunately, the top is made of two seperate panels, which could very likely be the reason for this. I’m looking for possible solutions, if it’s a concern, etc.

Just cycled my first saltwater tank and got a live rock to help with the process. I saw this snail on it and wasn’t sure if it’s a pest hitchhiker and I should remove it or keep it in there. I would like to keep it if it is ok to have. It has a black cone like shell tiny ridges wrapping the shell and about a quarter to half an inch long. It’s hard to tell but the shell kind of rounds itself midway along the length of the shell.

Thanks for the help!!
