Hello everyone, I have a 75 gallon open for now and will be buying a 125 gallon next summer. Would it work with the following fish?: (1) 3" Tiger Oscar, (1) 4-5" Geophagus Altifrons, (1) 2" Blood Parrot, (1) 2-3" Crenicichla Johanna "Red Pike," and either a 3" Shovelnose Cat or a 3" Rita Rita Cat. In other words, what problems do you think I might run into, if any, with these species in a 75 for about the next 8-10 months? Thanks!
