i really want an eel to add to the effect of my tang community. i realize this will be a threat to the multies in there, so i plan to remove them in that case. a plagistoma or a elipsifer isnt quite in my price range, but i still want some kind of mastecemebelus species. i was looking online and the zigzag (i think) as well as the zebrinus seem to stay at a relatively small size as compared to things like the fire eel. what do yal think? would they pose any threat to my cyprichromis?
