For me, having a bad experience with my possum that's still in my DT. So far it killed a corris, lubbock, pintail, pink streak, and fairy. I thought all along it was the damsel until I caught is killing the corris. all wrasses were dbl it's size as well. Planning to move this little guy out once I re-scape my DT then stocking up on wrasses again.30 x 23 isn't enough room for H. melanurus, in my opinion.
Possum or pink streak wrasse would be great options.
