They can tolerate it.. but it's not ideal, particulalry in the home Aquarium. the warmer water is the less capable it is of holding O2... granted I'm no expert either but I have kept them before as fry - 10" before re-homing them. I'de swing for a 60-70 frame. If your home is AC/heat. I'de turn the heater off and leave it to swing w/ your house temp. Live plants will also help your O2 levels in the tank. also by lowering the temp your cutting the metabolism of the fish, and they are voracious eaters to begin with. It will still grow like a weed, but it won't look emmaciated more often then not. unless you plan on feeding 5+ times a day. room temp, 6" range, 2-3 feedings a day should keep it healthy, and happy. they are fairly easy ime to get to eat Cichlid pellets. once he/she is settled in open the tank top... stand away a few feet.. and toss the pellets into the tank.. funny as this sounds.. it will often trigger their natural strike response and get them eating fairly quickly. I'de offer it some clean minnows/live worms the first few weeks so it'll settle in better, before trying this. and also hit him with a de-wormer, such as prazipro once you get it settled in and off live or takeing mostly pellets. Starveing a stressed out fish to force it to take pellets = dead fish. For a better idea of their needs, try looking in the PBass forums, and the Native Forums. as their filter/tank/ect needs are very similar ime. also I'de advise keeping the tank light off the first few days to make the transistion easier on him/her, and avoiding unneccisary traffic around the tank.
