Looks like a nice Grassy, they share a lot of the same characteristics as the chains. They both have fully scaled cheeks and opercle(gill flap). They both have 4 mandibular pores(holes on the bottom rim of the lower jaw) and they both have vertical black bands below the eyes, the grassy and the reds slant slightly toward the rear. The pattern of their markings is the real ID factor. Red's are grassys with red tails and lower fins.
