I got a Pleco to control brown algae in my community tank (3 female Bettas, 1 Pleco).
At this point, the algae is largely controlled, which leaves another problem: I need to increase supplemental feeding. However, I'm having a problem with the Betta fish eating the algae wafers (which isn't good food for them, and means that the Pleco doesn't get it).
How do I feed the Pleco without having the Betta fish eat all the food?
