South/Central American cichlid tank

In a 55-gallon 48x12x18 tank, how long would it take before a Jack Dempsey, Texas, and Green Terror-- all about 2" long-- outgrew said tank?

Also, those 3 species would be compatible with each other if they are similarly sized, right?

Very quickly. Providing they had good diets and great water, I'd give you 4 months at the most. I'd say 120 at a minimum when they get bigger, preferably larger. Those fish are somewhat mild, but I'd keep an eye out on the dempsey. If anyone was going to cause problems, it'd be him.

Voodoo, I'm leaning the other way. JDs are pansies when compared to GTs and Texas Cichlids, so he'd probably get beaten up first.

I've heard of that particular arrangement being done, but in a larger tank than a 120 as all three are territorial and they all need their space!
