Here is a picture of my cold water tank, to give you an idea this is what I'm trying to duplicate with two more tanks for tropical, one for the live bearers (guppies, mollies, sowrdtails and platties). I will also do a second tank with a sorority of female betta's with may be about 6-8 females containing VT and crowntails. I'm hoping to get some halfmoons somewhere in the future but being almost 4x the price of VT I'm going to see how well I go with the cheaper version first.
