I feel I have a responsibility to speak up for all pleco lovers. I myself am one

. Throughout this thread, I've only seen mention to BN plecos. Believe it or not, there are SO many other varieties of plecos and just as beautiful of fish as any other species.
It is a common misbelief that plecos are algae eaters. In fact, opposite is true. Many of them prefer meaty foods! This misbelief was undoubtly perpetuated by big box stores and unknowing customers, and has been an idea in the hobby for at least when I first started keeping fish 10 years ago, and probably long before then. The true diet of a pleco in question can be most often found using a google search, in which case, planetcatfish.com is generally the best source for all things pleco. Many are omnivorous with a preference to meaty foods. Some are omnivorous with a preference to vegetation. Others need to rasp on driftwood, and some yet eat what is called 'aufwuchs' which is the biofilm that is formed on surfaces of established tanks and houses a variety of plant and animal substances.
Plecos are poopers! But housing a pleco in a planted tank can be beneficial for the plants! Planted tank owners don't vacuum the substrate, right?

A well established planted tank will have plants rooted well enough where the pleco will not uproot them. There are a few that will eat broad leaved plants, but if given vegetables in their diet, they will mostly leave them alone.
Please give plecos a chance! They are truly a beautiful fish! These are just a few examples of how strikingly beautiful they can be.
