I have a pitho crab that likes to sit on top of the rock work on his hind legs trying to punch fishes. He’s been doing this for a couple of days now. None of my fish are harassing him and It doesn’t look like he’s trying to defend himself. He seems to be the aggressor here.
None of my other crabs are doing this. They’re all grazing algae like normal.
Any idea what’s going on?
