For 10$ it would be worth trying to save it. Keep in mind that it usually comes out and night and being black will make it all the harder to see. If you can train it to come out during the day it should be interesting to look at but not nearly as beautiful (IMO
) as one of the yellow or orange ones.
As long as you're willing to feed it chopped up pieces of food 2-3x a week (and you have to feed each polyp or that polyp will die not feed one polyp and it shares with the colony type coral) and your parameters are pretty good it should do well for you. Mine has not wavered in its beauty (yellow one) since the day I put it into my tank. I feed it Liquid Life, mysis and chopped krill 2-3x a week. I think, as long as you feed it, it is pretty hardy.
