Yeah this is true. All the other besides the mata will bite and take fish out if there are going to be any in there.
That's funny! The stuff I read online about their care recommended keeping 30-40 feeders in its tank for it. I'm not planning on keeping fish in there really. Thought maybe I'd try a common pleco for algae control and see how that works cause that wouldn't be much of a loss...(I know, cruel, but this is about as cruel as I get!)
