When I called him, he yelled at me, told me I needed to learn more about the hobby, informed me he was a Marine Biologist, and I didn't know what I was talking about. I have 2 other witnesses. So 3 total counting me. He informed me that the zooxanthellae from my green hammer transferred over to the yellow hammer. That is when he informed me he was a marine biologist, and he knew what he was talking about and I did not. It is not worth losing a customer over this. If it was me, I would have refunded my money and kept me as a customer. I asked Kevinpo, who is a contributor on this forum, and a moderator on Reef frontiers about his theory. He told me it is impossible for the zooxanthellae to transfer over. When it got here it was completely shrunk down into its skeleton. To me, it looked like it was not going to make it. It still looked lime green to me, but he told me he would give me 2-3 weeks OVER THE PHONE for it to recover and see if it was going to make it. So I thought the lime color would eventually turn back to yellow as he informed me it was BEFORE I purchased it. It took that long for it to recover from being in 50 degree water. It was probably even colder than that in Seattle.
