when i feed cyclops all my bristle worms come out too, they love that stuff. my lps dont close up, but my poylps all do, they love it too! ive never had a problem with it, but maybe u did get a bad batch, send them an email. maybe they will give u a bunch free like when i got a bad bag of dog food they gave me 10 free bags!
I have actually never used Cyclops before, first time, but it does stink ( more than most thawed fish foods). I have used a few other frozen foods in the past, with so-so luck. I really don't put my faith in these frozen foods. They always seem to produce alot of waste in the tank to me. The CUC sure like them all, but not really the fish. I know some people swear by them. Maybe i just have not found the right ones.
Cycopse is the stinkyest frozen that I've used if u want to swing by this weekend I'm not to far from u I we can compare Stank. Also can give u some different frozens that I use. what lps are u feeding. Pm me if interested.
