Nori is dried seaweed. You can get it @ chinese deli.
PB's s/b left to the most experienced hobbiest. They tend to be on the delicate side although once acclimated do fine. They are not as delicate as the achillies or clown tangs but are not as hardy as the purple, yellow or sohal.
How long have you been in the hobby? No offense intended but if you have to ask about nori, probably not too long. My suggestion would be to keep asking good questions, read allot and keep up the good work witht the tank you curently have. After a year or so of success, you'd probably be ready for a PB. At that point you'll need at least a 5 foot tank that is well establishedw/ l/r,l/s and protein skimmer along with a Q tank where he should be kept for about 3 -4 weeks before putting in display. The key to successful PB keeping starts with picking a very healthy specimen that is eating.
Mine eats everything. DAily nori, brine, mysis,clams, angel formula, spectrum pellets, etc. Everything is soaked in selcon, zoe and garlic.
