yes.. i dun advocate keeping those cleaner fishes.. they just dun survive in our tanks.. i had lost a couple of them.. one of them lasted 3 months.. they will feed on brine shrimps.. but after a while, they simply just die off..
however, the hawaiian or caribbean one is more hardy.. i seen one in at the LFS in balestier.. and it cost $40... a bit ex.. but it feeds on pellets and mysis shrimps.. and it goes ard doing the cleaning job as well..
as that is too ex.. i got something similar to that of Norvin.. and it was in my tank for the past yr.... and it got brave enuff to do some "cleaning" of my hands when i clean the tank..
however, on the whole, i advocate using cleaner shrimps....
