I just got a good offer on a tank if it turns out to be what the person says. Now my question is I have the fish I want to go in it already I want to know how long this stock could live in this tank I know most of the fish wont be able to be lifers in a 125 but these fish are going to live in a permanent tank together eventually. So heres my current stock (split between many tanks) 1 Tiger Oscar 11", 6 Silver Dollars 4-6", 1 Satanoperca Leucostica 6", 5 Gephagus Jurapari 2.5-3.5", 1 Indo Dat 4.5", 1 Jaguar Cichlid 6". These fish would all be added slowly depending on size and temperament if this could be a working tank how long would it work in the 125 before they all had to move. Also any suggested tank size for this stock to live together in for life would be appreciated. (would like to add a few cichla orinocensis to finished tank)
