Large coral colonies and adult surgeonfish in Key LargoWe aquarists try very hard to keep our animals alive as long as possible for a few reasons. The first is that we are caring people and don’t want to see them hurt. The second is that our specimens cost us a lot of money. Exactly how much money depends a little on the care we provide. For example, if we buy a purple tang for $100 and it lives for 10 days, then that fish cost us $10 a day to enjoy. I would say that is an expensive fish! But if that same fish lives ten years, then it costs us maybe around three cents a day (I didn’t do the math, but you get my point) MORE
