The answer is letter B. You should feed your Puffer fish twice daily. It is a fact acknowledged by fish lovers that anybody who owns a puffer fish should only feed it twice daily because they need to have a well-balanced diet in order for them to imitate their natural diet when they were still living out of an aquarium.
However, the seeker puffers should only be fed once a day while they are still young. Once a puffer fish matures, you can finally fast them once every two to four days. In terms of the kind of food you can feed a puffer fish, you can either feed flaked fish food for young puffer fish and pellets for mature puffer fish.
