some of you may remember about two weeks ago i posted because i bought an albino common pleco and the pleco in the tank was getting more aggressive. well they have settled down and seem to be buddy's now, there always together. well some of the responses i got were saying to feed more than just algae wafers, that was the first time i ever heard that plecos need more than algae. well i have tried different types of greens, cucumber, celery, kiwi, and lettuce. they dont even touch it. and i always leave it in overnight when the lights are off, and in the morning its still there untouched. any advice.
