My LFS has one in their display for the past 3 years. doing well. They report other's have them in their tanks for similar lenghts of time. I trust them quite a bit actually...
It's on my "must have list" but i'm waiting for a nice one to arrive.
The "trick" as i've read it is to get one eating. Once that is established, you're main concern will be collection practices... after the 6 or 8 week mark you should be good for the long-run.
BTW, there is a red-tailed version as well as a black-tailed version. All pretty nice IMO.
I feed 5-8 times per day and each day there is at least 4 different foods including pellets and frozen. I have 4 different types of pellets (FaunaMarin Color, Health, Sparulina & Energy) and a few different frozen including bloodworm, mysis, brine, cyclopeez and some marine-mash...
so there is -i think- a significant variety of foods... which is what I think it takes to keep fish happy and healthy...
When I put my potters wrasse in the tank I fed Nutramar Ova - aka fish-crack. Though hard to get here in canada, it works wonders. Also buying some fish caviar (bulk low-grade) works well to get fish started on eating... from there going to mysis and bloodworm was easy...
one last thing, i think having a group of agressive eaters (hungry fish) creates a feeding response from "lazy" or new fish... the energy in the tank goes up.. everyone starts to perk-up and look for their food... if possible, i'd want to add the fish in this secnario.
