I have been keeping SPS for a couple of years now and I have noticed at times when I get a new frag it will throw down a base that has little to no color. For example I got a hawkins frag about a month ago and it was already a little encrusted. The area where it was encrusted was all colored up. Since it has settled into my tank it has continued to encrust but the new base it is throwing down is more grey. The coral itself is still colored up it is just the new base. I have noticed this on my pink lemonade, red planet and ORA Borealis as well. The corals themselves are all colored up and when they become mini colonies the base will gain color. I was wondering if anyone else experiences anything similar. Was thinking it could be bugs bothering the base or maybe the new base growth gets bleached by my LEDs. Its not really a problem as everything is still colored up and growing nicely just curious.
