Surprisingly the sail fin molly I have in with the puffer a keeps up a good front so the puffer doesn't mess with it. But yeah about twice a month now my dragon forgets about the nippy puffers and digs under the divider... I will be redesigning my fish room soon and will probably set up a dual tank stand for my brackish tank. One for the puffes and one for the Gobi.
No pics yet but nothing has changed since my video at the start of the thread.
Thanks for your comments!
