So I decided to go on craigslist yesterday and I was looking for some new additions to my tank. I found a post for a couple of saltwater fish one was a yellow tang and a bunch of other fish is what the post said $50 and I have to take the 30 gallon tank and all the equipment these 6 fish were in. So I happily say ok I could use the tank for something, maybe put the damsels in it for my son in his room. So I get to the house and come to find out they are not damsels at all but here sits the Yellow tang,Pellet eating Mandarin, Regal/Hippo tang, Sailfin Tang, Misbar Perc clown and a Nebulous Wrasse, all in a 30 gallon with the entire bottom of this tank that has a cyano blanket and the yellowest water Ive ever seen in a tank. The fish were all eating and looked overall ok. The yellow tang is a little pale. All waiting for their new home. Of corse they are all in a 90 gallon QT. So I was just wondering if there is anything else besides feeding nori soaked in selcon and rods food to bring back his color. Also if any one has any experience with the nebulous wrasse and their care would help.
