Marine/Freshwater?
Fish Crazy
With everything everyone has told me about this species I was hesitant at first about getting one. Really they are very hardy. The tank has been at 78 degrees for the past 2 months. Really this species is not sensitive to abiotic factors at all. they just stress and burn oxygen ridiculously. Mine has had the biggest wounds of any fish I have ever seen and lived! The only real issues have been paracites, oxygen, and tankmates. My had been nearly eaten by sea lice. Freshwater dips worked. To rectify to oxygen problem I use the turbulence from a skimmer/filter. Peacock puffers are not aggressive they just pack so much punch, not only are they fast, but they have massive jaws. As long as someone can provide them a stimulating stress free home they are tough as nails. At four months I think I have things ironed out with this fish. The reason these fish are so hard is because people worry so much about their fish that they constantly have their hands in their tanks. These are not difficult fish. They are just easily stressed.
