Bully fish

Okay, Delta died. I have no idea why, but he did. So we got a new fish named Syan. He's a big purple guppy. And he's a bully. Within one day, my first fish, Delray was hiding under the fake rock thing with about half his tail missing. It was probably Syan, but it could have been the filter. Syan's getting all the food because Delray's too scared to come out. I'll give it a few more days, but Syan may have to go. We're gonna take him back to the pet store and get a new, non-aggressive fish.
