I have two types of frogspawn and their tentacles always seem to get really short in one of my tank. I had both of them in the same tank until recently I took one of them out and put it in my other tank and the tentacles got longer again. The only major difference in the two tanks is that the tank with the frogspawn that has longer tentacles has T5HO lights and has less flow compared to the other tank. The tank with the frogspawn that has shorter tentacles is lit by LED fixture. The only thing I can think of is that the one with shorter tentacles is getting too much light or too much flow.
