that's great
just so you know, the reason i'm asking (and 1journeyman was thinking the same thing i'll bet) is that one mandarin will most likely starve in a 30 gallon. 2 most definitely will. your 2 bags of pods would have been eaten in about 3 days if not sooner. A fuge will give the pods a breeding ground, but still, a 30 gallon won't have enough rock for the mandarins to eat off of for a very long time.
the warranty will cover the shipping death, but you're money won't be reimbursed months down the line when they die. just my $.02
