Thanks to all for all the info. My fish all are doing well, although by Saturday, the water was like 67, so that really scared me! I went ahead, and purchased some 300 watt heaters and doubled up on the heaters for all my tanks, just to get the temp up to 78 1-2 days. As of now, water is 78! I am sure thy would have all done fine, as most fish have a recessive gene, that allows them to survive cold temperatures. Of course in the wild, only the stronger ones would survive, but thanks to modern sceince, and high quality foods, I am sure most captive cichlids would do fine in the low 60's, maybe even high 50's? But just having the thought in the back of my mind, that these guys are "tropical", I let my caring side overule my scientific side, and that "what if" question. I forked up the money for extra heaters, and just took that route. I love cichlids, especially CA cichlids, and I did not want to run the risk, of loosing any, including my beani, that I brought back from Mexico. Thanks again everyone, and have a very Merry Christmas and/or Happy Holidays!
. I have 12 tanks going right now.
