At least, I think so - and that's the topic I'll be discussing at the next meeting of the Tropical Fish Society of Rhode Island (TFSRI) meeting, on Wed May 19.
Basically - I think that anybody who can keep freshwater fish truly happy - thriving, breeding, etc - already has all the skills they need to keep saltwater fish happy, with no more effort or work - and I'll show you how.
For directions etc please see http://tfsri.net
