well one of them is not a fish its a frog, my adf died while he seemed to be perfectly happy, and my goldfish died but he was like half alive when i took him out, i think the killer was the tiger barb he's being really violent all of a sudden, what happened? anyways he's going back to the store TONIGHT! :mad2: big meany. any who hopefully it was his fault and not something wrong with the water. what r some signs i should look for in thte ohter fish as poor health or bad water?
