Most of my fishes are from Pacific Reef aka ah Beng..the oldest tang with me now are my blue tang pair (got them at smaller than a 50cent coin)
some tangs n other fishes are from TFC, LCK201 & reefers..
I will always say this same thing..when it come to life, I believe in luck n fate..maintain your water standard n dun anyhow dose medication..feed them well n enjoy admiring them for as long as they live in your tank..good luck ppl..cheers n happy reefing
