well let me be a little clear, I don't want one... never have, never will, just kinda want to see one in person... I wonder if Sea World of Texas has any.. .I might have to go spend a day there soon.
Sadly, far to many reef fish are being collected by an unsavory method using cyanide. The collectors toss a molatave cocktail of sorts into the water and it stuns the fish. And then these severely traumatized creatures make their way through the supply chain, and most end up dying on the person who buys them, and everyone loses out. This is why it is important to make sure your supplyer uses only those collectors that go down and collect by hand.
The real attrocity, is it damages the area of the reef and those species that are not collected as well, the phillipines are severely devestated by this, and many of their reefs are completely destroyed.
Thankfully, many fish have entered cultivation, but there are some that it is just currently impossible to breed in captivity, because they go through a plantonic stage in their growth, and various other reasons... thankfully, many nations, including the phillipines (I think them any how) are taking a conservationist angle and have passed laws against cyanide collecting, and are training their fishermen to work in such a way as to preserve the reef as a renewable resource.
kinda cool... that hobby is turning around and becoming more ecologically concious.
