If I had a larger tank I'd say a powder tang. Those are the prettiest SW fish in the hobby, IMO. Sure, they're a challenge, but once the challenge goes out the door, so does my interest in the hobby.
Right now, my must have fish are either the clowns for their symbiotic relationship with my BTA (so cute to watch one anchor itself by sucking on a tentacle) or my scooter. I love the fact that he's self sustaining (I don't have to feed him), ich resistant and his eyeballs move all over the place.
Agreed, I'm starting a nano (with just rock and a pair of clowns) because I love them. :headbang2:
Oh and I love your avi. That stinking Abominable Snowmonster is what I collect in terms of Christmas decorations. i need to now watch it before going and buying more corals and tank and stuff for nano.
You can't go wrong with any of the marine life but my personal favorite maybe a :
1.) red sea blonde naso male with streamers.
2.) powder blue tang.
3.) orange shoulder tang
