yesterday i was at my lfs and i saw ottos and thought that they would be a good addition to my tank because the pleco that i have cant get into the small nooks that have been made by the lace rock that i have in my tank and he seems just to stay in a few places and i need someone to get rid of the little bit of algae on my plants.......but would they be all right with what i have in my tank? decided to ask on here to make my wife happy because whe was like "i dont think you can have them in your tank. you need to ask someone." so here i am asking.
