I only have bad luck with expensive fish... we've seen alot of diseases in the tank over the years...
Now that we have cheap fish, a sebay clown that was $7 and a maroon clown that was $20, we can't seem to get them to die. I really want a plant ledge where the tank is built into the wall. I won't do anything to kill them, but every time I think one of them is getting a fish disease, it gets better. We've had these two nameless fish for about 3 years now.
Every now and then I go up to the tank and threaten to name them. lol
