I have a radiata lionfish who has become quite aggressive in the last few months. Tankmates are a valentini puffer, plesiops betta, ribbon eel, and dusky jawfish in a 73 gallon tank. The lionfish recently stung the betta (who has luckily recovered) and stung and killed a foxface. It acts aggressively towards everything in the tank except the eel. Does anyone have any tips for reducing this lion’s aggression? I don’t have the space for another tank so right now my only options are to sell the lionfish (which I really don’t want to do) or divide the tank somehow to isolate the lionfish. Thanks
