Fish Tank

So I have a hobby of keeping a few fish tanks in my house. I have had several different fish throughout my life, but the ones I have had the longest are the few I have at the moment. I have two freshwater puffer fish, their names are Rusty and Owen, two angel fish, named August and Asia, and a wierd black and white fish, his name is Carlos, and a sucker fish named Guy. I watch them alot, for some reason it interests me so much that I even talk to people about them. One day my boyfriend said that its like my own little soap opera. And it kind of is the way I talk about them. Carlos is kind of the bully fish, the other day he ate Guy. And the puffers well they are just wierd, they just swim up and down the tank all day waiting to be fed again, sometimes they spaz out and start attacking the other fish, not enough to kill but bad enough. The Angel fish mind their own bussiness, they are not much fun to watch. I recently bought a new toy for the tank, it is two barrells connected with a few holes in it for the fish to swim through. Rusty and Owen seem to like it the best because its dark in there and they can hide from all the other fish. Today Rusty got stuck inside the two barrells turns out he's to fat to swim through one of the holes, I had to get my net and help push him back through. One of the puffers is actually going insane, he sits and bangs his head against the heater of the tank like hes trying to hurt himself, I dont think he likes his life. Carlos just hangs out in the dark corner next to the filter, I think hes a murderer.
