I deal with hybrids myself and temp really does not have any effect on the color of my hybrids such as my female rose queen or her mate which is a male red head synspilum. Water quality does as well as what you feed them. Any hybrid Cichlids I have with any red or orange color to them I feed them krill and Monster KOK extreme red. Its good for parrots,flowerhorns,red Texas, and South American cichlids. Its fit for most tropical fish and will improve the immune system with stronger,healthier,and livelier results. I get my bag for $23 at HOT and its worth it.
