Some corals will reproduce once they mature.Make certain your water parameters and lighting is on point and in the meantime research and decide which species you like.
How much coral should I buy at first? Will it reproduce? How do I place the live rock in the aquarium? Sorry about all of these questions guys... lol
lol. My in laws have a rather large reef tank (I think something like 500G) and have professionals do it lol. It's amazing though.I tried a reef rank once and while extremely beautiful and mesmerizing, i hated the maintenence! Absolutely hated it.
