i have a BIG pink cucumber in my tank. I never should have purchased him, but I was a bit misguided by my LFS. He has been doing a good job keeping my DSB clean, but now he is climbing the sides of the tank and curling up at the surface. I am a bit worried because everything that I read says that if he stresses he can kill my tank. This is causing me concern and I am considering pulling him out. Is this crawling on the sides of the tank something to be worried about?? How do I insure that this guy is gettting food? Will my blue legs crawling on the cucumber cause him to stress? Any help from an experienced cucumber keeper ould be great!!
