Nevertheless, "algae wafer" is a misnomer for the Hikari product. If you want something for your truly vegetarian fish (bushynose pleco, otos), take the Wardley discs. If we are talking about common plecos who eat a mixed diet, the Hikari fish meal discs might be the right thing. I just want to make sure that you know what you feed.thus more protein than in the "vegetarian" style :grinyes: better growth and health.
