The two werebettas danced around each other in the water. There was nothing else going on, there were no other fish about in the dark sea, just the two brothers, dancing. Every so often, they cackled as they danced, but there was no context to what they were doing. They were drifting in a vague line North from their location, but that hardly mattered here. There was nothing, no landmarks, no directionality, nothing but these two souls.
Presumably they had scared off any other fish that may be in this area. The two didn't seem all together in the head and they flashed sharp rows of teeth every so often, suggesting they didn't only hunt for food. Currently, their movements weren't hostile or aggressive, but they were constantly looking about, staying aware.
