I have a cleanse wrasse in each one of my big tanks. The wrasses eat everything offered.. Including the nori. I've has the one for about 2 years and the other only a few months.

Mostly LPS And softies. few SPS.

I've always had good luck with cleaner wrasses however I was told how poorly they do so I bought a neon goby instead. Ironically the neon goby died shortly after I got it and the cleaner wrasse I bought after that I've had for over a year now. Also know a few other who have had good luck with cleaner wrasses, all of them were eating mysis in the lfs before buying them so that might make a difference.

I've had both neon and sharknose gobies and they have always provided a cleaning service for the other fish
