So I've never kept these fish, I see they often have Goby attached to their common names, but aren't actually Goby's... been seeing Empire & Peacock available for sale... very pretty & unique fish... curious if the captive Empires are straining natural sources, as it sounds like they breed in Fresh Water, but the fry are washed down stream, & juvenal's are raised in salt water, or at minimum brackish water... so it sounds like they are at best very difficult to breed in captivity... besides Empire & Peacock, does anyone else have one of the other varieties???
