My father has a 150 gal
tank with three fish in it, my 5 year old 12" panther grouper, a 10" spotted grouper, and a 10" coney grouper.
He feeds the live shrimp from a local bait and tackle shop, and the fish love them....live, saltwater shrimp are of course much better for them than the rotten ones from the grocery store, and anything beats goldfish, so this has been their diet for about 5 years. I am afraid though that the shrimp have brought lice or some other parasite into the tank that is causeing the fish to itch themselves.
Now I gave the panther grouper a freshwater bath on time when I got him, and he didnt like that very much, but stuff did drop off of him in the bucket.....this was 5 years ago when he was 4 inches long......Im not going to try this with his size now.
The fish constantly itch themselves on the rocks so he says, and asked me if he could put a cleaner wrasse that he saw at the LFS
in the tank to eat the parasites. The guys at the LFS
told him to go for it, but he wanted to ask me first. My father lives in another town, so I havent seen the fish first hand, and I am sure they are in no immediate danger, just a little uncomfortable perhaps.
Would this work, or would the wrasse simply be another meal? They are some VERY hungry boys.
