Hello! I have an established saltwater tank with a neon blue goby I’ve had for probably 4-6 months now. I got a neon orange goby today (it’s a 30 gallon with plenty of live rock so I thought they would have room to get away from each other), and while feeding I noticed they were staying close to each other & would follow each other. The blue goby would get very close to the orange one, sometimes stir up some sand, and they would both wait. One would go into a cave and the other would follow, then a moment later they’d come out again. It doesn’t look like fighting to me, no nipping or anything. Just wondering if this is a sign of (attempted) breeding? They’re different species and I know it’s difficult to breed them. Any ideas?
