My fish was happy until now. I noticed she would dart back and forth erratically, sometimes jumping, and would get red streaks on her body. A week ago I noticed white bumps and thought maybe doing a natural ich treatment would help. During treatment she got worse since she started sitting in a corner not moving or eating. We completely cleaned that water, and she finally seemed better, but now she’s not wanting to swim or eat. Does she have something serious? Should I clean her water again?
My fish has droppy and I'm very scared for him. Please tell me how I can cure this effectively and fast
Goldfish with swollen side. I read that it might be able to be treated with epsom salt. Did not want to do without checking on the accuracy first.
Hello, My RES's eyes were swollen for last 5 - 6 days, But now they look fine but still not eating as usual, environment condition is same as before and I am giving taiyo turtle food.

Hello . Can I give my dog trout fish or Tilapia???
After using metronidazole 400mg×2 tablets in 75 litre aquarium tank, my two parrot fish has thread like some seeing near gills and genital area ? How to treat them ?
I bought this goldfish last week and it has had a small growth/bump on its fin since then. It has grown slightly but not dramatically. He is still active and eating well. I have been thinking that the growth is a fungus and am treating with pimafix but judging by the way it looks I am not 100% sure it really is fungal. Does this look like a fungual infection or something else?
Hi, My fish has white spot which is expanding. It also has something around mouth. Spot looks white with small dots in it. I thought it is an ich outbreak. Currently tank is treated with Sera omnipur (30% of recommended dose). It is big pufferfish. thanks for your help Nikola
I noticed bloat in my flowerhorn about two weeks ago. It was there when I fed him and went away when I didn't. So I treated him with Epsom salt soaked pellets, bloat was present then. Then I noticed white poop so I stopped feeding entirely and added metronidazole 400 to the tank. Didn't work as I only saw white poop, so I added the medication into his food and now I can see brown poop hanging from a clear poop sticking out of his butt. Earlier the poop didn't stick out of his butt. What to do?
My gold fish got white spots on her fins and body and she has got red spots also. The white thing looks like fungus. 7 of my fishes died due to this. They became slow and just sat down and slowly died. Just one left plzz help. What can I do?
