Ok everyone it's been a long time since I have posted but I need help figuring out the stages of aggression in fish if there is any I have a predator tank in the living room and just discovered that my porcupine puffer ate my horned cow fish. The tank has a massive stars and strips puffer, a baby dog face puffer, porcupine puffer, snowflake eel, and was a horned cow fish. These fish have been together for over a year and all "hangout" no fights over anything not even food they all eat krill. A few days ago the porcupine puffer slowed down with his eating to the point he almost stopped and noticed today after work that the cow fish was gone and now the porcupine has been acting very sick. Mind you these two use to swim together take turns eating etc etc no bite marks no fights no aggression in the tank at all. I have had huge success with all these fish and only had to feed one type of food. Is there a stage in the porcupine puffers life cycle that causes a weird aggression. These fish never show territorial aggression and honestly all rest bundled up near each other. Also the porcupine has kept himself distant from the others when his eating slowed down. Please help so I do not make a mistake again, if I missed something important in the life stages of a puffer.
