The captive bred list is growing and we are so lucky to have what we do. it wasn't long ago that it was clownfish and maybe bangaii.
Biota does sell captive bred flames
Bonus is you get to see a fish grow from a tiny juvi to an adult and morph in color and body shape and you know that fishes age and that it can live a long life if well cared for.
I do hate shipping fish as it breaks my heart to see them die, there is no LFS where I live now so that is the only option most of the time but I do make a 2 hour drive south to pick up fish now and agian.
I will say that many fish still die in shipping.. to whole saler... to the LFS... to you... so in reality... it's just not seeing it in front of you but it's still there.
Sorry, thats not an answer to what you wanted, the opposite really. I buy wild fish but will purchase captive when I can.
The fish that do make it into tanks... if they have a good keeper will have lower stress than in the wild.
If you can buy diver direct (basically KPA's Caribbean fish) they probably don't have much of a death rate there. They are netted and don't travel far and you get an
exceptional specimen that you know is free of cyanide and not starved along the way from far off places.
Also some fish are much better shippers than others and choosing a vender to supply them is important.. and proper quarantine.
This is my latest addition from Fishotel, went in today, hour later he’s out and eating (the spots are just particulate in the water, no filtration or sump yet).
