Pufferfish sand spitting?
Recently my Stars and Stripes pufferfish has been exhibity some very strange behavior. He is grabbing mouth fulls of sand from the bottom of the tank, spitting out half, and shooting the other half out through his gills! He ends up wearing some of the sand atop his head. Is this harmful to him? I'll admit, watching him shoot sand everywhere is entertaining, but I don't want to see him do it if it is bad for him.
Any ideas why he may have suddenly begun doing this or whether it is harmful?
Thanks so much!
