I have a 125 gallon fowlr set up with 2 small clowns, a damsal and a Picasso trigger fish, those were all doing good no issues all young fish, then a few days ago I introduced a 3 in long foxface and a blue spit puffer also 3 in long the Picasso is the same size as them. The first couple days was fine now the foxface is hiding in a cave and the Picasso is glass surfing and won't stop all of them are still eating. Water parameters are all good, what can I do to calm these guys down? Been going on for the last 2 days
