Yea i would like to put ricordea as a sand bed and couple of other coral in there but since is only 8 and 14 gallons i dont know if it will be alot! and about the light like how much more would i need to upgrade in order to maintan all the coral that i get? and what should i feed them or give them in order to them to keep growing and alive. cause i have always had bad luck with coral! so thats why i decided to go with a BioCube!
