I need a yellow fish to balance out the coloration in my tank. I'd love a Yellow Tang but I feel my tank would be too small. I have a 48 gallon that currently holds 2 clowns, 3 Green Chromis 1 Cardinal, 1 Diamond Goby, 1 Fire Fish, and 1 Royal Gramma. Any suggestions for a reef safe, peaceful, yellow fish I could add to a tank my size?
