Does anyone know anything about the really little pleco's about the same size as oto's? Parotocinclus spilosoma is what I think they are. They are small about 2" and have not grown at all in a couple months so I don't think they will get much bigger. They were amazing at getting rid of the brown algae. I bought a couple when I was having a terrible brown algae problem, before I found this forum. How hard on plants are they? I was told at the LFS that they had them in a planted tank with no problems but I am doubtful. I have one left that I haven't been able to catch and move to my other tank and wonder if I am going to have to tear things up to find him. I see a few small holes in the leaves on some of the plants and think he may be the cause since I only have a 6 tetra and 1 pearl gourami and 3 cory's other than him.
