Praise indeed Ivanhoe!, and Alan.
Viper, yes they are Evansi. The first ones I got a year or two back just diappeared into the reef never to be seen again.
These came in Kenyan shipment by mistake, and I threw them in, but the difference I think is Fish Roe, they love the stuff. I think that its almost a requisite for many Anthias/Psuedoanthias.
Thanks guys, I will put in some pics of the systems that drive the tank tomorrow.
