i have two young cresteds, and im pretty new to this. i know enough to understand thet they are to young to be sexed, they are in seperate 10 gal. tanks untill i know more. but one doesnt stick to anything as well as the other. basically when i try to hold or remove one, my smaller yellow one is gone in leaps and bounds. but my slightly larger orange one will leap and stick to the tank but very soon after it seems to slide... not sure why, any ideas?
