The puffer unfortunately went carpet surfin yesterday. However, he never went neat any of the inverts. He couldnt get near the tiger because of the gobie. Bur NO never an issue. Your best bet is to do a Toby puffer that is relatively small. And yeah, my star is not doing well. He got caught up in the powerhead. He's healing and getting better. Was thinking about dropping him in my sump to heal.
