I just (Finally!) found a few (3) Zebra Otos. They have only been in the tank for 2 days, but they seem to be doing fine...at least one of them finally found the zuchinni! I know that they do well in larger groups and I would prefer to keep only zebras, but I can't seem to find any more of them anywhere, only the "regular" oto vestitus. I just read on a webpage that I could keep more than one type together, because they won't interbreed, but I just wanted to run it by the forum. Will they interbreed if I get some more and put them together?
