Wow. I had typed a response that was 3 paragraphs long, then I mistakenly hit the back button. Damn it. It was good too, it had a lot background info on how the true green terror just recently became available again.

Blast it all. I guess it is all for the best as my post was a bit off topic anyway. It is still sad though.
If you are interested in knowing why the true green just showed back up in the hobby around 5 years ago, shoot me a pm.
If you want basic husbandry information then you should find what you are looking for by searching the forum..
But since I would be annoyed if I asked a question on a fish forum; only to be directed to the search function...
Here is some basic info.
They are south American fish which occur in both Peru and Colombia. In the wild they live in relatively fast flowing streams, but you shouldn't worry about trying to duplicate that environment in the home aquarium if you get properly acclimated fish. Males will hit 11" females should reach 8". You could easily spawn a fully grown pair in a 75 gallon tank as long as they are well bonded. IME they are on the lower part of the scale when it comes to aggression, I consider them to be in the class of jack Dempseys in terms of aggression and physical capability.
