I have a Porky and Humu Trigger in separate tanks. If you have them in the same, keep in mind they have different eating needs. The Trigger needs to be fed 2-3 times A DAY while the Porky NO MORE than 2-3 times A WEEK. Puffers are very affectionate and people like to feed them, but overfeeding can damage their liver and cause them to "rest" all the time because they are digesting. My proky is healthy and happy and very active and is only fed twice a week.
My humu on the other hand, while also happy and healthy, is fed twice a day from a variety of frozen squid, krill, clam, mysis, trigger formula, VHP cubes, shrimp, Angel cubes, PrimeReef, silversides, and spirulina cubes. I also put seaweed in the tank once a week, which he gobbles down, and once a month he gets fresh raw seafood like mussles or cherrystone clams from the grocery store.
Both, well all, of my fish are so healthy. I recently had a confrontation between my Angel and Sharpnose puffer in which ended with the Angel having a HUGE gash near its gill, quite deep and gross. Within 3 days you couldn't even tell anything had happened it healed so fast.
GOOD LUCK!
