I completely understand your concern if you think i just bought the fish, but i have no reason to lie and, even though you state you are not accusing me of anything, am quite offended.
The thread to me was good, my books are not very detailed and i only hooked up to the net last mth so i'm not a pro at using these things (i find it easier to keep my Moorish Idol alive).
Anyway, i have next to no coraline algae and for some reason never have(maybe he is eating it). I have put sponges in the tank and he doesn't touch them either. He eats everything else i put in the tank from frozen food, all pellet and flake food and his favourite is "Spectrum Thera+A Large Fish Formula" ( which i have almost got him hand feeding).
Its a shame you don't live in Brisbane Australia as i would let you see him everyday to prove it.
What else can i say????
