could do a smaller pike cichlid, I would do a fh in a 75 it will be fine for years if not life... so many nice fh to choose from if your limited on regular cichlids... I like faders and golden monkeys although I'm defo no expert on flowerhorns they rarely get over 12 inch ime!-)
Thanks for the advice guys. Ive pretty much narrowed it down to either a red devil, GT or flowerhorn as they would be the easiest to come across in Australia. I'll keep you posted/ put up a pic when I get something ☺
