I just got a rubber-nosed pleco for my tank because all of my ottos kept dying. I got him/her because the guy at the lfs told me that they were really good at keeping the tank clean, and they don't get too big. I have a 10 gal tank. Well, my pleco keeps hiding, and I never see him come out or stick to the aquarium walls. He just keeps hiding inside a decoration so you can't see him. I don't know much about these. Is that normal? Will he come out after a few days?
you need to do something about the situation in your tank if you want to stop your fish dying. You may not know this, but Mollies can grow up to 5 ".
