Tried pink zoas, b4. Used to put them at the top of the rockscape, cos I thot pink likes more light. Anyways, had them for a while then they melted away. Not sure why.... But I have seen pink zoas in other bro's tank and it placed on the sandbed and it's doing well. So this time, the pink one I got from Iwarna's last shipment, half put on sandbed and other half in the newly scaped tank, under 250w mid tank. Will see what's the difference.....
