I have a 20-gallon fish tank, and these pictures show what it looks like 2 days and 6 days after cleaning. The water seems to be turning green, and I’m not sure why or if this is normal. What could be causing this, and how can I prevent it?

I want to set up another fish tank [would be my 3rd one, I already have a 10 and 3 gallon]. However, I'm worried about the evaporation. My parents think setting up a 3rd one would make there be too much water in the house [???] and I'm trying to show them there's barely any evaporation. How bad would you say your evaporation is, and does it actually screw up the air you breathe in your home? Thank you!

I found this thing on my tank glass today, I was wondering if it was planaria. Anybody knows what it might be?

So I recently upgraded to a 20 gallon long and now I’m trying to figure out how to scape it. So far I added about 1/3 ish of fluval stratum and two liters of controsoil. For species currently owned I have 3 amano shrimp, 5 khuli loaches, 4 otocinclus, and 4 neon tetras. I have some mopani wood that’s being waterlogged and from my old tank I have spider wood a 3 plants (buying more), and some small rocks (river stone size). I could just buy another bag of fluval but I don’t know if I should maybe try using sand. My tank is essentially black so maybe black sand? Does anyone have any recommendations? If sand isn’t needed then how many more bags of fluval would you say I need? All of my fish have always been on fluval but I’m trying to go out of my way to improve their quality of life more. Since I’ve gotten a new tank & am buying new supplies.

I’ve never used sand so I don’t know how to go about cleaning it or how much is needed (unless I can add it straight in).

Swordfish chunks as food

Hi everyone. I am starting my first fish tank soon after receiving a 20 gallon tank for free. I am not sure how to start, but I did some research and I think I want Neon tetras, male platies, cherry shrimp, some nerite snails, and some plants such as flame moss. Will this work and if so, how do i go about adding everything in? What will I need? I don't want to spend a bunch of money, maybe $200 max if possible. What are your thoughts on this?

Please someone identify these flies, I assumed they were young mosquitoes. But apparently not, they will NOT GO I’ve done mesh, full cover, surface agitation, the infestation won’t go.

Apologies for the bad picture they are tiny!

I was looking in my Tiger Badis tank and found this little guy! He is probably half a cm big

Hey everyone

Fat fred, whom we know is fat fred due to his dominance at feeding time and how fast he stuffs himself... well today the idiot ate a large crab cuisine pellet, which is HUGE. Picture of his hikari micro pellets vs one he friggen ate, which

Moving forward, ill add pellets for shrimp and snails at lights off i think...fat fred quite literally got up in the mystery snails face and into the shrimp pile on and stole it from all of them. Rude.

Anyway, fat fred, as you can kind of see in my terrible photos, is bulging and lumpy. He seems ok, though he is flapping his fins alot and his gills are moving rythmically in quick consistent beats...he is still acting normally. Its been about an hour now. Airstone is running, water parameters stable and hes been in this tank about 6 months.

Other than not feeding for a few days, can i help him at all? I cant believe the little dickhead ate it 😰

my mom has gotten two fish from the perry fair today. I have nothing, I think they are shubunkin goldfish, they pretty big already. I know that they need to be in a big tank and etc but I can’t afford a 75-100 plus tank and really don’t have room in my house for a big tank. Can someone help me with what I need to do. I have no idea but my daughter wants to keep these fishes.🥺

Ignore the music lol. I found 2 baby shrimp while I was doing a water change. I noticed them swimming and put them in a glass cup. I have 2 fancy goldfish that would most likely eat them. I’d like to keep them and have them grow. However, I have no idea how to take care of them. Any tips. Thanks
