I’m getting a 20 gallln tank and I would like to know what are the best tropical freshwater fish that I could get? I would like to get a pleco, but he would get to big for my tank, so I’m wondering if I could donate him to my locomotive petco in The Dalles Oregon? Thank you I love PetCoach!!!

I found really small fish in a freshwater pond and dont know what to fees them . What should i do ?

All of my fish died after using a product purchased at Petco called ACUREL-F. How do I get their water safe to put in new fish?

I have a freshwater pufferfish and he isn’t eating the fish flakes like the other 6 fish in the tank (red tail shark, clown loach, and tetras). Do they need to be fed live or frozen food? He also butts into the aquarium walls here and there. Is this caused because of stress or anxiety? If so how can I fix that as well.

I have a freshwater fish in my aquarium that I cannot identify. It resembles a Mosquito fish but is lighter in color, thinner, swims differently, and has what appear to be sparkles on its sides. I caught it with a net in a school of mosquito fish but it is different. it was the only one in the school that looks the way it does. I found it in the shallow part of a lake in Florida. Please help me identify it.

Two of our freshwater fish are acting oddly in the water. We did lose a few last night, due to an ammonia spike. We noticed some pale-colored, wormlike flesh dropping from the front area (between the mouth and front fins); this black Guppy is “wobbling” around... We also have an orange Molly fish that has been staying on the bottom, not eating or moving much. Attached are pics, for your review. Can you please provide advice for these issues, we want to try our best to save them!

I bought my fish at Petco last week. The day after I got her, I noticed a swelling on her stomach. I’ve done research and found that most pictures point to dropsy. I’m in college and need the cheapest course of action to help her.

I have recently used medication in my 50 gal freshwater fish tank with one 22 year old comet goldfish in it . the meds cured my fish but must have killed my beneficial Bacteria as now my established tank has been going through another nitrogen cycle. It's been four weeks now the ammonia us back to zero so is nitrite zero BUT my nitrates are now spiked about 80 and the water is cloudy. Did 2 partial water changes over the last 8 days. Will a UV sterilizer help ?? Please advise. Thanks Lina
