Is it a sun coral or dendrophilia? I'm used to seeing dendros out more during all hours and sun coral behaving more like you described.
Google ans do research on a pink branching dendro and you will find the information.
i have had it for a year now so it must not be too finicky because it would have been gone by now lol..
Bump for still available
ditto.....:thumbsup:Would love to see a picture when open
