Had him about five months Now. Dewormed, eats fine. Must have been In his holding tank too long, not growing. No longer skinny, nice plump and healthy. Would be great in a 55-75 gallon tank. Gets along fine with my cats, not aggressive at all. Throw some offers. Wanna tear down or redo my 120g. Thinking 75 shipped, 25 if you can come pick him up which I would prefer but I do have his insulated box from when I got him if need be. Little Guy just woke from his burried under the sand nap and had some snail snacks. Always excited to eat. I've fed worms, clams, snails, squid, mussels, all with no refusal. He's a happy little Guy, just seems like I have an empty tank with such a tiny little fish in there. I'm looking for a 1-1.5in baby so I can be sure it grows. Either that or ill tear my big tank down. Can't find anything to compare to a puffers personality.
