Planning on setting up my tank in the future, waiting to move first. I want to have the least amount of impact on the natural reefs as I can. Corals will be easy, as frags are everywhere, and the rock will be all DIY with few pounds of rubble to get things going. I am thinking this rubble would even be pulled out and returned to the LFS so I can say that nothing came from the actual ocean. My qustion is what fish breed in captivity? last time I had my reef I remember the only thing in there I could confirm were captive bred were the clowns. The Tangs were wild caught, this is what I want to avoid as much as possible.
