Been kicking around the idea of attempting to possibly breed my red head gobies any tips for sexing/breeding them. The one fish i have had for 2 years his head is a lot larger I got a second rh goby about a month ago. Its the same size but way smaller head. They get along great in my 40l but I noticed each does have a "territory" and they do visit each other but after a bit its back to their own spot. I am working on setting up a frag tank and wanna put them in their for breeding. Lay a few pieces of pvc for laying in. Is their anything else I would need to do to get them breeding assuming they are a pair? Do they raise mostly like clown fry?
