Glad you brought that up Vip.
That is not neccessarily true although that statement could be. In a poorly set up SPS tank or depending upon the coral in question, that could be the case.
A platygyra Brain will rarely grow more than a 1/4 inch a year under excellent conditions.
My WebpageOn the other had here are two pics of a Montipora Capicornus. The first pic is a frag thats about the size as a Siver Dollar. The second pic is about 8 months later and is about 8" across!
My WebpageMy WebpageAs you can see from those last two pics growth of SPS coprals can be extremely rapid and depending on the coral painfully slow. It varies on the coral being kept anf the conditions under which it is kept. Lighting, water flow conditions and available nutreints will all play a major roll more times than not.
Before much longer I hope to do a species profile on several hundred fish and close to that in corals! Of course Rome wasnt built in a day and neither will this project, but I am chippin' away....
One of the biggest hold ups has been a source for sharp close up pics. I have located a source for many thanks to MDM Aquatics permission to download and show case some of thier Copy Writed pics from thier website. I am still working this issue with Barry at Clams Direct and a couple of others.
