Good lord, tonight I tried something that I shouldn't have. I tried to add a 12" porc puffer in with my queen trigger to give her some company because she's been really jumpy lately. I stayed on standby not knowing what to expect - the queen nearly killed the porc in seconds. I put the porc in and kept the queen trigger away with my jumbo net. She darted right for the porc and almost went through the netting. She backed up and went around the net. The queen latched onto the porcs tail and shook it around and the porc puffed up thankfully and the queen let go. I would have never done this if I knew she would have been this aggressive. After the puff deflated I netted him and put him back in his tank. He is fine, probably a bit stressed. My wife was almost crying because she thought he was going to be eaten. Take it from me. NO FISH CAN BE KEPT WITH A QUEEN TRIGGER. PERIOD. EVERYTHING ELSE IS FOOD TO THEM!
