thanks so much everyone for responding to midgis post with such great info. seems like she has some rare ones. I am alot more familiar w/ SA Cichlids, so i really havent been much help at all except to go watch them "play". I am about to look up full grown size of each of these fish to see what a good size tank to look out for in the future. My guess is BOB will probly get around 16" or so, so id go at least a 75 an up. i saw a craigslist of a fish breeder closing out, so maybe we'll have to make sum calls!!!
Midgi, you are very creative with yor tank design, I really think they are happy. don't let it bother you too bad when they do their rearranging, I think it is enjoyable to them to have stuff to move around!!!!!
