The Puffer Forum

I had been a little concerned about my 4" Fahaka because his belly always looks full. After observing him for a few weeks I have noticed that he is eating sand and passing it through his system; only to eat more sand (pool filter sand). I was wondering if anyone else has observed this behavior or could foresee any possible health problems.

mine huffs at the sand when he is hungry. he will look at me, then go to the bottom and huff a bit away, then come and look at me agian. then swim to the top of the tank.

I know some puffers eat small stones. Here's a topic about the same thing.

Thanks for your replies. They put my mind at ease.
