I recently purchased a dwarf Gourami, It is my first one. He was fine the first couple of days, but now he has a rather large belly (I think its his stomach it might be a swim bladder or the wierd labrynth organ)and is acting rather sluggish. The only thing i might be able to attribute as a cause would be the feeding of baby brine shrimp to the tank. The day after he ate the baby shrimps i noticed the problem. I dont think that it is the cause, but he may have potentially swallowed lots of air, or something, and figured it was somewhat relevant. does anyone have any ideas on what could be going on with my dwarf gourami?
