hi, I'm new to this, but I have a question. 2 1/2 years ago, I picked up a 27 cent feeder fish from the local pet shop. I wanted to "save a life," but as he is growing, i have established that he is definately a fancy goldfish. Butch Cassidy lived in a one gallon tank for a year but then he developed airbladder disease so I bought him a 2 gallon and switched him to sinking food. He still didn't seem happy so he now lives in a 10 gallon tank by himself. I go to college, so Butch travels in my car in his 2 gallon. (He used to travel in a cup, but he outgrew it.) My question is, am I doing anything wrong. I use AquaFresh because I use tap water. he has gravel, three fake plants, a rock to hide in and a bubbler. He lives in natural light, farish from the window, but not very far. He is a big little boy (at least from when I got him), but his color has gotten lighter. A few of his scales have also fallen off. Should I get him pH stuff and a filter? Any help would be great. Thanks.
