That's quite an impressive list of aquaria LOL. I plan on starting with some small cichlids. I love the managuense, so I'll put one or two of those, then add a couple green terrors a red devil, firemouth, dempsey. The usual cichlid stuff. As the jag gets bigger I figure I'll have to either start getting rid of fish or get rid of the jag. I'm just excited to be able to get the fish I like and keep them for a while. I had a 55g, a 45g, a 30 g and 2 10g (feeder tanks) and those tanks really aren't big enough to keep anything for a long period of time. I plan on getting a 30 or 45 for my son, he wants to keep one of the piranha. I also want to get a couple 10g for feeders again. I like to sain minnows out of the creek for feeder fish (plus sometimes you catch some bonus fish to keep in the tank).
