I ordered I ordered 7 from SWF.com for like $25 ea. Four died within hours of arrival. I had them re-shipped. Within about a week all but three were dead. I think one of those died within six months. Out of 11 fish, only a pair survived a year after purchase. It was all a matter of shipping and stress. I do not recall ever seeing any sign of disease on any of them.
The pair NEVER EVER come out of hiding when they can see me. I have had them for about two years.
I've kept almost every clown on the market at one time or another and these are by far the most difficult I have encountered. If I were you I would save my money and buy something else. They're easy to find but the odds are against them surviving. If you can find tank raised, I would get those.
