We've got two! Ours are call Smaug & Smeagol.
They are fairly easy to took after (for a puffer) as long as you are happy to feed live foods. and hoover the tank after every feed.
Dragon Puffers (t. palembangensis, also known as the Humpback Puffer & the King Kong Puffer) are true freshwater fish. They are ambush hunters, hiding in plants or caves until something tasty goes past then *WHAM!* they lunge for it.
They are one of the most inactive puffers, spending all day sitting on the bottom, often looking worryingly dead. (I've had to poke ours a few times, just to be sure!)
Dragons get to around eight inches and so will need a fairly large tank, although because they are so inactive, they don't need huge amounts of room.
Food is anthing meaty that moves such as live shrimp, jumbo bloodworm (jokers) fish, small crabs & crayfish.
They can be weaned onto frozen mussels, cockles & shrimp, but it takes a while! We've had ours for months and they're only just beginning to show interest in frozen cockles.
They have amazing colour changing abilities, especially on their bellies which can be dark spotted then go pure white in an instant depending on mood.
They can not be kept with other fish. Small fish will be eaten and larger fish will stress these timid puffers who may attack when under stress.
We have been succesfully keeping two Dragon puffers together. Sometimes they chase each other, and sometimes they cuddle up together in a cave.
Need to know more? just ask!
Ours cost about £37, so I'd say yes, $19 is a good price.
