I've just recently added a Pictus and a Hoplo to my tank. Hoplo is OK but i've got a chinese algae loach (Gyrinocheilus aymonieri) and he seems to have taken a dislike to poor pictus. Loach is about 5 inch, both Pictus and hoplo are smaller. I understood these loaches can be terratorial with their own kind - am I mis-informed, advice please.
