Hey guys! I was wondering if anyone knows what this is about... As we all know, firefish have a long dorsal fin that they can erect or lay flat and every time i go near the tank they sort of flick the dorsal fin up and down in what looks like a warning to either predators or the sort. Is this a defensive posture? Is this to warn me, the "predator", off? I'd love to hear what you guys think. Thanks!
