No Problem Peter, I had them in a 55 gallon tank but I would defenatly go with at least a 75 gallon tank if you can afford it. You are going to need A TON of filtration, and as far as feeding them when they are babies start them off on frozen blood worm, when I first got them I knew NOTHING about keeping fish....but as for feeding them I used a combination of flake food, dried blood worm and dried baby shrimp. as far as feeding them as they get older I fed mine live feeders
