The tang is definently more at home now. He has started eating OSI pellets, which is a good thing, considering he wasn't touching anything but nori and algae on the rocks.
Not sure what you see that looks like a gourami, what you see there is an Atlantic blue tang,
Acanthurus coeruleus; a Potter's dwarf angelfish,
Centropyge potteri; a Bicolour blenny,
Ecsenius bicolor; an Orange diamond goby,
Valencienna puellaris; and a pair of Black saddleback clownfish,
Amphirion polymnus. The blenny is really hard to see on the rocks. I expect you're looking at the angelfish. He is a really nice fish.
Jon you can't get out that easily, I'll find something for you to fix.
Maybe you'll have to help me cull the GSPs, I swear they've grown by 1cm on each side since I got them.
