I have 6 cichlids that I got at the same time, they have all grown significantly. When I bought them they were about one inch now all but one if about 4 inches. There are two albino zebras, two electric yellows, one normal zebra, and one electric blue. One of the albino zebras is still small, he/she eats, defends his/her little corner of the tank and otherwise seems normal. Any suggestions?:help:
