I have a lawnmower blenny and an urchin and snails to help deal with the algae. I'm wondering if I should be feeding my blenny macro algae in addition to the algae in the aquarium? If I do feed him macro algae, what type of algae do I feed him and secondly will he still eat the algae in the aquarium? Finally if I do get macro algae how often do I need to feed it to him?
