Its almost time for a new addition to my tank, need some advice. I was reading about hair algae and I'm considering a blenny to help control algae. I have 4 turbo snails and hermit pack from Doc. fos'n'smith in a 30gl. the question is I have a clarkie clown, maroon basslet (fridmani pseudochromis?) and a banded coral shrimp. will a blenny be able to hold its own?
