So I have been pretty lucky when it comes to algae. There is virtually no algae in my tank. Not sure if I have to thank my plwco for that or not. Anyway, I feed him an algae wafer every night before bed. Usually when I wake up, its gone. The past few nights, it looks like he hasn't even touched the wafer, and its breaking down on the bottom of the tank. Is he tired of wagers and I should feed him something else? I have tried cucumbers, but he doesn't touch it. Any suggestions?
