Hello. I have had 3 Indian mudskippers with some mollies in a cycled 35 gallon. So far everything has been going smoothly but today, along with my shipment tragedy (RIP $100 worth of fish) one of the skippers is flashing. He is out onland when he does this and I have only seen him do it on this one piece of cork bark. Makes no sense. Do they do this a lot of does he have parasites/some other form of irritation. Is he just wierd? He is still acting like the same aggressive alpha fish he was when I got him just every now and then he flashes. Any ideas?
