I got 1, 2" jag yesterday and went back to the same place and got two more today and already I notice odd behavior between two of them. I dont know how to really explain it. One grabbed the others jaw and pulled it out of the hole of driftwood they are in. Then they kept taking turns getting in front of each other and "backing " the other out of it, all while gills flared, but nothing really violent. There is plenty of room for them to hide. My question is, is it just territorial, or could they have paired off at this age?
