Semi aggressive is a little if an understatement I'd say. Mine are very adept at catching fish and just generally all around psychotic lol. They will charge at me even.. I'll hear the claws clinking the glass .

My blue crays didn't kill any fish for maybe 2 months . They get bigger more aggressive and smarter over time . I have mine in a 46 or 48( can't recall ) . Anyway I stocked my tank properly for living with the crays . Rosy barbs and golden wonder killifish . But several molts and a couple months later they learned how to get to the top and ate all the killifish. I'd keep a super close eye if I were you. How big is your cray right now?
