as mentioned above. bought a green panthom just recently and i always see **** on it although it doesnt eat alot or eat anything at all... y is that? bad sign or normal to plecs?
they care called algea eaters and waste makers. before they would tell you to buy one because it eats dirt. actually it makes dirt. i had several plecos and i just don't like it when they leave all the mess. to consider it was a bare bottom tank that's why i saw all the things that i didn't when i had gravel. it depends on you if you can live with it. if you have several plecos i would do more water change and have a bigger bioload.
