I had a 65g freshwater for 5 years with many different American cichlids in and I had a brilliant flowerhorn cichlid (female) she would eat out of my hand let me catch her by hand when she was unwell, then she spawn and she was so territorial but she would let me lift the top of there cave to have a look at the fry.
I now have a 65g saltwater and my cleaner shrimps and peppermint shrimps all are hand fed and they clean my hands and arms it's quite ticklish
( my fire shrimp just hides
) and I have 6 black and White clowns and they all have there own personality
So I have to agree I think it's just a fish thing not a saltwater thing but in my opinion saltwater is more exciting
