I've been wanting and planning to get a larger tank for some time, but can't decide how big I need to go. I have two 55s right now and want at least a 125 if not a 150 or even 180. In the short term, I'll be putting a Poleni and JD in the bigger tank, but obviously want to add other large cichlids. For those who have bigger tanks do you have any advice, any regrets with your choice?
