Thanks guys. I knew I could count on all of you. My seahorses love to hide in the macro algae or branch rock. I want the coral to add color and give me something else to work on. Feeding and phyto are not a problem. I will start with photosynthetic species until I learn more. I've read WetWebMedia before for other things and did not think of going their for coral info. Since many of the enrichments I use for my seahorse foods were originally designed to feed corals, I should have plenty of food on hand. Thanks again. Cheryl
