I have a very well established Angel/Discus tank. I have had 4 Discus and 6 Angels in it for over two years now; I saw some interesting Angels in there and I purchased two large ones. I told the owner the pH of my water was 6.5 steady, and he said that so was theirs in the store. Two days after bringing them home they died, and he refused to give me my money back, even after I brought them a sample of my water (which checked out to be perfect as it is a few year old established aquarium). They do not quarantine their fish at all, and you risk serious injury to your tank if you buy from them - NEVER GO HERE. If you want to buy fish who are GUARANTEED healthy, go to OC Tropical. The owner is very helpful and his fish have all thrived in my tank.
