Please feed your fish!!!!!!!!!!!!!!!!! Anyone that has a Naso Tang that is slow growing has either poor water quality and or poor feeding!!!!!!!!!!!!! Your average Naso that you purchase at 4" in length should be pushing 12"+ within 1 year. Your average feeder goldfish reaches 12"-18", but in reality they are usually feed a crap diet and live in dirty water and reach a measely few inches in length......Alot of marine species that we commonly keep have life spans of 20+ years, when you purchase your "little" fish they are a juvinile!!! as in "baby" expect to still be caring for them when your kids have left home.your Naso possibly led a very short life with a major in starvation. Naso tangs should look like a football and are very expensive to feed!!! I should start a new thread about this epedemic in our industry.........I dont mean to pick on any one person, I think most folks strive to care for their livestock but fail due to misinformation, and simple iggnorance(they just dont know). at least with forums such as this one, we as a collective can help educate one another.
