Omar has a nice 6-line wrasse which you can borrow for while. I know he doesn't mind me saying this because he hasn't fed his wrassy since the last Hari Raya. So if you could catch it by your own, the wrassy would be a great help in erradicating your nuisance nudis. After the job has finished, you can goreng the ikang buat sambal tumis !! ... whee weet..
