I am wondering if teacups are compatable with an Oxydoras niger catfish? The catfish will be about 4" and the rays will have about a 6-7" wide disc. I am posting this here because my concerns are that the "spikes" or whatever you would like to call the boney projections that are on the sides of the catfish will scrape the rays and cause infection and everything for the rays health will go down hill for the ray from there. I understand that I will have to make sure that the rays are going to be still getting food and whatnot, but I am just concerned with weather the catfish will deliberatly and/or accidently harm the rays? Any and all help is greatly appreciated!
