Kitten = Milk Cat = Fish (Raw or cooked) Overgrown = Don't Eat
Cats like tuna and salmon the best of all the fish. However, it is really up to your cat as to which kind of fish is his favorite.
cat fish eels peranas (take it from a person who has 5 big fish tanks with 150 fish)
there is no particular reason that your cat fish swims upside down but it could just be the kind of cat fish you have. it isn't abnormal for a cat fish to swim upside down because some can only swim that way.
