Ive kept scolymia now going on a year.... def noticed that the first few I had started to lose tissue for no apparent reason after several months. At that Time I began feeding and all have rebounded. Its my opinion that scolymia require food source for long term health. I think many people keep them for months with no issue, but the lack of food catches up and they begin to die with no apparent reason. Again just my experience, but I have multiple health scolymia that are now growing in size, and all i can attribute this success is due to feedings them (2 times weekly). I use mix of pellets and then reef chili or reef roids.
