Hello all, I recently purchased a pleco to go along with my gold fish to help clean the tank. I have 3 koi and 8 regular comet goldfish in my 30 gal tank. Everytime I add an algae wafer to my tank for the pleco, all of my fish besides the pleco, all pile around the wafer and devour it before the pleco gets a chance. My pleco stays concealed underneath a fake rock the whole time, I've never seen him anywhere else. What I'm asking is this, Is it ok for all my goldfish to eat the algae wafer in addition to their regular feeding? and is my pleco getting any algae since the other fish seem to love it? I don't want to everfeed any of them but whenever I add a wafer to the tank the goldfish swarm it before the pleco even gets a chance. I'd like to see the the pleco do his job rather than hiding under a rock the whole time. How can I resolve this? Thanks all in advance.
