My dwarf puffer is sick...HELP!!!

[Kronk]

A sunken stomach usually means internal parasites which are very common for DPs. I had couple batches of DPs all of them all had internal parasites when I got them and lived for a little over a year.

As was mentioned they are small but need a lot of room and a LOT OF PLANTS if they dont have enough plants they get stressed and exhibit symptoms similar to yours.

I used to visit this site a lot good info http://www.dwarfpuffers.com/

Here is a pic of my old setup

Good Luck to you they are definately my favorite freshwater fish.
