Welcome to MAAST. Grats on the new tank. Food for thought: A tang really isn't a good first fish for a newly cycled tank. While Kole tangs are hardier than say Hippo tangs, tangs in general aren't as hardy as say most gobies or chromis, etc. Especially if this is going in > 100g I would save the tang for later. Adding a bigger fish at the beginning can cause another cycle, ammonia spike.
