Hey! Just picked up a few corals from a friend. These are my first corals. My 49 gallon tank has been up and running for about 6 months now and no problems at all with fish. He gave me a few little polyp chunks, a frogspawn frag and a pretty decent sized leather of some kind. They have been in the tank about 12 hours now and my lights have been on for about 2 hours this morning. The two smaller polyp chunks have began to open up and are about 50-60% open. The leather however shows only the tips of a few polyps starting to poke through. I drip acclimated the corals for about 15 minutes last night before i put them in. Just wondering in other peoples experiences how long it takes for a leather to open up in a new aquarium. Thanks!
