I have my 3 in a 10 gallon with a heater, a plant, a filter and a hood with lights. They are eating algae wafers that I have for my Chinese Algae eater. They get lettece alot to. Two of them have grown a full set of legs the othe has stumps. I dont know if the feet will form later but I am thinking he might not morph out. The two with fully form back legs though they are still small are always hanging out at the heater and are larger than the other one. I am not giving up though till they die or morph so this should be fun. Any advice is welcome though.
