Yes the one i posted was a pinatus bat fish also called a red fin batfish someplaces , I did not have any trouble with him in my reef tank at all , they a very pretty as they mature they loose there red stipe a bit and as u can see in the picture i put up the center starts to get more gray rather than black which continues through adult hood ,
must be kept with very timid species i would say, since they do very poorly at competeing for food also they like
low water movement not big pumps coming directly
into the tank since there tall fins are very delicate and have a large surface area , excess water movement stress's them out and they don't swim against th current as well
