Sorry Goodwin I have been remiss in not finding this thread until page 37 of split #4. So I'm quite sure my question was answered elsewhere but I wasn't able to find it with search.
How tall is your 450? It looks taller than the 600 but that may have just been an illusion of the photography. If it is 30 or 36" do you prefer that depth to the 24" depth of the 600, wish you'd gone shallower/deeper on either of the tanks?
Thanks!
BTW, very jealous of your beautiful array of tangs. Every so often I get into some of the other fish families but honestly... I think tangs will always be my favorite.
