I was wondering about my Firefish Goby this morning, can Firefish breed with Helfrichi's or Purple Dartfish? I know Flower horns are the product of breeding 2 or 3 fish species but I'm super interested in what the marine hobby has to offer for different morphs in species. I'm very interested in the possibility of pairing two closely related species together to breed as well as symbiotic mutually beneficial relationships that don't involve breeding like gobies and shrimp, cleaners, and much more.
