Awww, so sorry for your loss. Was the tank cycled and everything? Puffers are notorious for being very sensitive to water changes and chemicals.
Not all the time is a skinny puffer the result of parasites. All four of mine where emaciated when I first bought them because they didn’t get the appropriate diet at the petstore. Took them all a solid week of eating before they looked healthy.plah831 said:ooh, he looks very thin and sunken in. dp's often have internal parasites. luckily mine didn't, but that picture looks a lot like puffers with IP's that I've seen at dwarfpuffers.com
