We have four of these, two big and two small. With in the last few days I have noticed one of the smaller fish is less active. Today I took a good look at him/her and noticed a few things. The tail and top fin are in bad shape. They look chewed up, but I don't think any of the other fish have done this. The fish is yellow and I have noticed that his sides are looking a little brown.
Any advice? Also how do I find a store with an experienced person. When I lived with my parents in high school I had a great aquarium and a really great guy who owed a store near by. Now we live across the country and I don't know how to find another great person to help.
Thanks
