This is news to me yet it does sound plausible. The only thing in the tank with my Croceas that need feeding are nps gorgonians, so I guess as a precaution I will move the gorgonians to another tank since they requite constant feeding.I can tell you that feeding ReefRoids can definitely suffocate a clam though I'm sure others will say that's impossible! I fed ReefRoids and my (2) blue squamosas immediately closed up and never recovered. I don't feed that in my tank with my clams anymore. I'm sure they will say there's no connection, but I had my (2) blue squamosas for 6 months and had no issue with them until I put ReefRoids in that tank. I don't put that in with my clams anymore.
