Well I am going to eventually pick up Rostato's 90rr set-up. I am kind of torn right now on which direction I want to go with this one. On one side, I am going to eventually have the tank mainly SPS dominated. BUT, family members have been whispering in my ear that they would LOVE to see seahorses in the tank and even offered to fund them. I am unsure of seahorses because I never had any experiences with them. I am about to do some SERIOUS research on them. What all kind of tank mates can they have?
