I don't think they will ever be $20 again (or even free...I remember getting yellow tangs for free with the purchase of another fish, lol). Inflation and all the other craziness going on in the world has raised prices on everything. BUT, I don't think they'll be the same price as tank bred either. I think we'll see prices more in step with where other common tangs are...$60-$100 would be my prediction. Might not happen right away, but once we see a reliable supply of lots of fish, it will happen.
