My beautiful new zoos look like fashion models. The longer they are in the tank the taller and thinner they get! I'm no longer sure they are going to survive and I have only had them about two weeks.. Anybody know a solution?
They are high in my tank - under 260 watts of light.. 10k PC
and Actinic. I have tried moving them down but that did not seem to help. Water parameters show no ammonia, nitrite or nitrate. pH 8.2 and temperature rises sometimes to 80 during the day and falls to about 76 or 77 every night.
