Here's one of my Knight Gobies. I think it's a male - can you guys confirm that? When I first got him I thought he was a she, but his fins kept growing, especially that dorsal fin and my two seem to be spawning every couple of weeks.
Thanks! That's what I thought, but when I got him I thought he looked like a female and so did my lfs guy, but he really blossomed. I've tried to get some pictures of him while they're spawning(which now that I say it makes me feel kind of dirty) because his fins blacken and he looks amazing.
