What'll happen? I like the look of it but plan on using it in a non-salt water tank for some electric yellows cichlids in a 55 gallon (approx. 4 feet by 1 foot). Does anyone happen to know what type of rock live rock is? I'm thinking black background, white sand and live rock formations for a faux salt water set up. I want to go hard and get a monster fish but not now. ANY feedback, constructive criticism and advice is always appreciated.
