I think a bit of an increase in price is to be expected. I feel like 200 average makes sense considering the scarcity and that that's what the biota ones are selling for. it might even push towards captive bread tangs becoming more common in the hobby.Too late!! My LFS has a Small-Medium sized one for $165
After that, the $400 yellow tangs is just people being opportunistic with a terrible situation. The price will go down when things become more readily available. And the ban is most likely not forever.
