Coral Colours and Amino Acids

[kien]

I think you also have to accept that some corals just simply shock easily from having been established and was used to one system (aquarium), and then all of a sudden being shoved into a new one. It can take them a very very long time to regain their former glory. Some may never achieve this and some will colour morph into something different. It is not necessarily a matter of bad parameters, but rather different parameters and conditions from what they previous were used to. Take your red coral turning pinkish for example. It is virtually impossible to reproduce ALL the parameters and conditions of their previous tank. Some corals can adapt quickly and easily, some (or perhaps most) do not.

I have a coral right now that was once red, then browned a little, now has coloured up with half of it being blue!

my 2 cents.
