I have 5 of these tetras in my tank... I tossed a tiny piece of algae wafer in there for the pleco, and the tetras went NUTS. they loved it. do they eat algae??? or were they just eating it because it was there?
There is more than just algae in the wafers so the tetras will eat it. As a general rule though, tetras won't eat algae except as a last resort (like if you went a week or 2 without feeding them).
My tetras pinch the granules I drop in for cories, its funny as they alway pinch the biggest piece and then go hide behind rock spitting it out n chewing it.
