I wish I had stuck with Dojo loaches! Don't get me wrong, I love my plecos, but they are FILTHY! Before I got my BN plecos, I only had to clean my Penguin filter every 6-8 weeks, and even then it wasn't bad at all. Now, after only one month, the biowheel was slowing down considerably, and the water level in the tank was good, the tube was more or less clean, so I cleaned the filter and YUCK! So much gunk, I couldn't believe it. Its a 20 gallon with two BN, 3 inches long. I already have one BN in my 55, and am going to moving one of these out of my 20, into the 55, and I'm HOPING this will cut down on the gunk in the 20. I guess I was spoiled before. Now I feel like I have to watch the biowheel like a hawk. I got them partly for algae control, and because I like how they look, but I'm not sure if its worth it, with all the mess they make. To me, the mess almost cancels out the algae control. If you had a minimum of a 40 gallon tank, I'd say 1-2 at the most might be okay, but no more!
