Ok is it a bad idea to keep a common pleco with a sting ray. I have a female henlei, and a 12in common/regular pleco, and he follows her around the tank pestering her. Any time she settles down he will start landing on her and I guess he is sucking on here coat, so I removed the pleco, but is this common? And if so are there any other sutable replacements for the pleco to keep the algae off the glass all the time.
