Haha well the pleco is between 14-16' long. I got him about 2 days before I got the butterfly koi. I'm feeding him algea tabs, but if yall have any other suggestions to keep him full let me know! I just don't see him being fast enough to catch the butterfly's but who knows haha. What do you guys suggest feeding 1-4 inch butterfly's. The pellets I have for my large Koi I believe is to large, they seam to nibble on the algea wavers I put in for the Pleco...but I really want to get food they will go nuts over. Thanks yall!
