mandarins are a beautiful fish and not relatively hard to care for, as long as the aquarium has a really good pod population, which normally means having a good sand bed, and some good live rock, and letting your tank breed pods for a while(like about a year) b4 getting one, 1 mandarin can dessimate a pod population fast, and most will not take to feeding, and to help out a bit more, in the archives forum, ther is a thread called slang assistance, which i posted back in december of 01, which has a good many terms that we use here, youmay want to look it over there are way too many to memorize, but if you get the jest of some, alot of others will fall into place
