Peacock bass all the way mate! Got 6 of them in my6ft tank they are brilliant it's a 900 litre set up with 5 ft sump they take a lot of work but are worth it I've had mine from fry at 1 inch big within 4 months they are now 6 inch if not bigger and colouring up nicely, I've got a friend who has got a 10x10x5 pond in his garage that breeds them he's got peacock bass in there pushing 1 feet long they look awesome, that's who I had the fry from as I know he has good stock and they are not hybrids that most
