i've had my common pleco for about 1 month, and he is about 7" long in my 55 gallon tank, and he refuses to come out and clean my front glass for me. he always hides on the back glass and in the rockwork. i've never had too much luck with plecos before, because i keep my tanks too clean, but now its pretty dirty and he isn't cleaning anything.
is there anything i can do to get him to come out and clean my glass?
i'm considering just getting an oto, but im scared that my juvie cichlids in the tank would kill it
also considering a chinese algae eater, but i've heard that they don't even eat algae
what could i use other than the pleco if he won't clean my front glass?
