well, there are quite a few people breeding them in captivity - supposedly it's not hard - so barringhabitat destruction, hopefully their numbers will be safe in the wild.
i thought that they weren't as endangered as we thought, we were only looking at one part of their habitat...? Not sure on that, just recall reading somehting like it. Anyways, I love mine, though "celestial pearl danio" is a stupid name and most people don't don't what you're talking about unless you say "galaxy rasbora"
I looked into this recently as I was interested in them. The most recent stuff I found said export of them from their native country was banned. They also found more ponds with them in, including some deep in the forests.
It'd be safe to say that young fish are going to be captive bred, as long as you get them from a reputable source. They're also not as close to extinction as people thought.
As far as the name goes, I have to wonder why they didn't just call them 'Galaxy Danio' after realising the rasbora mistake. Or is there a galaxy danio already? Who knows, but celestial pearl danio is a bit of a mouthful.
