Wow, you got a crazy mix going on there, man! Since everyone else covered all of the possible compatibility issues already, I'll just say this...try to target feed the puffers with frozen food 2-3 times a week if you can. I've had many customers come in with dead puffers to return and I hear a common thread through all of their stories, that is they were told by someone I work with that puffers will eat flake food. Now maybe some species will, I guess, but I've never seen any of ours eat flakes EVER and when this person tries to give them flakes on one day and I come in the next and give them frozen bloodworms they are ravenously hungry and attack the food. The worst part is that certain someone giving some bad advice out is my boss.
