i have to agree with Nlz
Naso tangs get big around 18 inches which is about 45cm they need a tank that is very long for swimming space IMO at least 200 gallons to keep them happy and to provide them with swimming space
for hosting you can use anything that they like the look of they will choose what tickles there fancy. but some good choices would be leather corals as that is what mine hosted in. i think they will host in almost any coral. but i would stick with soft corals with your lights and the less...
when its hot like last summer i bought an air conditioning unit that u put freezer pack things in (much cheaper then the other types). i placed it sought of near my tank so the cold air blow around the tank. worked a treat plus it kept the room cool for me which is a nice bonus
iam up for it i have a few bits and bobs to be fragged.
the only question is would u take the coral to your local post office and ask for the next day delivery? or will they pick it up from u?
