I've had him for about 4 months and about 6 or 7 weeks ago I had what I think were gill flukes in my tank. I put the medicine to kill parasites into the tank as directed and every thing went back to mormal. But now my pufferfish is sitting on the bottom of the tank, and he won't eat anything. Even when I put the food right in front of him he just stares at it. For about a week he hasn't been eatting as much as normal but I figured that he just wasn't hungry. Then today he stoped eating all together and sitting on the bottom. I've been feeding him freeze-dried
krill. My water parameters are ok, nitrates are about 20, nitrites are 0, and
pH is 7.6. My water temp is around 76 and the
salinity is a little less then 1.004. I recently started adding salt to my tank becaue I realized my puffer needed to be kept in brackish water. I had the salinity at 1.002 for about a month and then rased it to 1.004 yesterday. Is he having a problem ajusting to the new salt level? My puffer is in a 30 gallon with 2 ottos and 2 siamese algae eaters, all of which are fine. I was wondering if it could be indigestion? If so, how do I fix that?
