I often notice that one of my local fish stores gets in yellow scorpion fish (rhinopias?) every now and then in pairs. I was observing two of them together and I display tank and the smaller was pressing up against the other. Overall they were doing some weird things but it seemed like they had some sort of bond. Well I know not much is known about these fish for their mating habits I wondered if there's a reason they tend to get them in pairs and if the pairs should be kept together. Here's a picture of one of them
