yes you have to be a very patient person to do this hobbie, nothing is fast all pretty slow as far as coral grows... I've lost alot of coral stuff just happens things get out of wack and boom it's dead , you have to test for calcium , alk , mag, and a bunch of other things, coral require a certain amount of all of those things , but I've had alot of The same stuff in my tank for 4 plus years now!
i havent GROWN coral but ive had a salt water tank for over 6 years now pain in my fucking ass is what it is...beautiful though..
I has me A NEMO!
