jbittner,
I do as much research as I do working on my tank(s). I need not click on any link to where ever. All websites are just like the marine species themselves, they are subject to opinion based upon experience/individual study. I've done quite a bit of background research before considering my options. Some websites swear up and down that the dragonet is so resilient to disease that in near perfect conditions, it's virtually immortal. Others have said that the dragonet HAS been bred in captivity. If that's possible, why haven't I seen them?
You know what? Come to think of it, some "I"DIOT from one of those Petcos told me that their mandarin was bred in captivity. Of course he also told me pirahna was saltwater fish.
Anyways, $12 dollars for a mandarin is no loss to me, especially if I could train it to eat frozen food. I could have easily turned around and sold it for 3 times as much.
Nevertheless, Mandarins CAN die of ich, I know this because...
my second one did. After 5 months, I just gave up. I couldn't figure him out; couldn't get him out of the tank; always hid in the rocks; the food cope/amphipod even isopod population was plentiful.
