Hi, I bought 2 wood shrimp about a week ago and the woman from the pet store has accidentally put a fish fry in the bag with them he made the journey home and is in his own tank, however I’ve never dealt with fry before I have the food for him he seems fine but I don’t know if he will get lonely on his own and if he’s eating enough also is there any way of knowing the breed I think the shrimp were with mollys or guppy’s at the store.thanks.

Hello i have a fish tank 45l with 11 fishes in it (Shubunkin , opaline gourami , honey gourami , trichogaster etc) . i added the fish a week ago and tested the water and it was fine.today i see that 2 of my Scalars aren't eating like everyone else , so i tested the water . Everything was fine except for Nitrite levels that was 3.0 - 5.0 ppm. I changed 25 % of the water and added Easy Life Filter Medium and after some hours i tested again the water quality and it was the same I also added salt

I have two male fish guppies. One of them seems to have like a wired black spot on its belly (in the middle of its body). Is this normal? Could it be a disease? Any cure to this? I’m worried. Also it has a little bit of white on its tail :(

What type of fish can I keep with my adult male betta fish, he is in a 3 gallon tank.

Why does my Betta fish have lines on his gills?

I dont know if you are a tropical fish specialist. But there is something going on in my tank and need help diagnosing it. My corydora has two raised growths ..one at the base of its fin. And one under the eye. My pleco seems a bit tattered too. A little flashing was happening with my yoyo loach also. That's now stopped after a water change.

One of my fish has open sore on both sides of the skin. Apparently some of the other fish has bitten him and now some of his skin is bulging on both sides and it’s in a 70 gallon tank with other fish, and I don’t know what to do.. can someone help me..
