They are new to coral and they have just 1 tank of corals. There corals are basic, mostly sponges and lps. There prices on the coral are reasonable. I have never purchased any corals from them, so I don't know to much about there coral. Although there fish are very nice. There prices are cheap and there fish are always very healthy looking. They can also order anything for you. They are very nice people as well. I hear nothing but good things about petshack. I was in there last week and there was a couple that drove 2 1/2 hours to get there. You should check them out you won't be dissapointed.
