Convict Cichlid named Jeffrey, whom I hate, he's nothing but a nuisance, I'd flush him, but I'd feel guilty.
I used to have a HUGE beautiful male peacock, but he died of some kind of fungus that didnt respond to treatment, 2 boring jewel cichlids that I used to cycle my tank when I first set it up, they looked ratty when I bought them, and an electric blue crayfish, who died just last month during his 8th molt, he couldn't get his claws out of his shell, and died of exhaustion.....poor thing
I don't know if it's a good mix for expert enthusiasts, but the pet store here didn't tell me that convicts suck and not to get them, and I'm still learning about what fish are good with what.
Oh, and I have a 29 gallon vivarium with a fat White's tree frog in it.
