GAH! I have the exact same fish! One of my friends gave me her tank + fish! GAH, i never knew what it was till now...oh horrible, it's a cutie but poor little guy.
And to think i wanted to get him a pal...
Iam totaly against dying fish, but even as many times as i explain to people that it's not their natural color and that they can contract diseases easier they still get them. It's best to tell them, if they dont listen let it go, you did what you could. It's supply and demand, tough world we live in, sadly we're surrounded by a bunch of stupid people too(not ya'll, the brain child that decided he needed to color his fish).
This supports part of what nmarc3627 said.
EDIT: Your fishies are gorgeous BTW
, forgot what i was posting about after that rant.
