@Carpman wow! That's interesting, and a little sad. Poor kitty! I always thought a fish tank would be like tv for a cat, something mellow to watch.
@Changing4Best I wish I could take your tetra. I take care of a tetra tank at school, which includes the kind you have. I found out that tetras make great tank mates for other tetras, and they come in so many colors and varieties, so I put about 20 in a big tank with snails and pothos growing out of the tank. Did you know that pirahnas are the cousins to tetras? They are fierce little guys, but they understand each other.
