I'm looking for a bit of help in trying to diagnose just what is happening to my betta fish, Herbert. He was purchased June 29, 2013 - so close to being a year old now! - - He seemed to be very healthy and happy.
We moved to our new house in November '13, and I slowly changed his water over to our -well- water. It was a gradual change from city water that *was* hard water, to well water that for the most part SEEMS to have less iron in it than the city water.
I've kept Herbert on a pellet-based diet (Tetra Betta pellets), and we have started breaking them up and feeding them to him after seeing him have difficulty eating one whole. He used to be fed 3-4 pellets 2 times a day, in the morning before work, and at night after work.
About 3-4 weeks ago, I started noticing his stomach was looking just a tad bigger - the coloring was just a little lighter, so I knew something was off. We started giving him less pellets gradually, and last week on we were doing about 2 pellets twice a day. The last 3-4 days however, he is eating less and less; today was my breaking point with him not so much as even doing his hungry dance for anything. He ate 1/4 of a pellet and 1/2 of a blood worm I tried feeding him just to see if he would eat.
He is very lethargic and spends most of the time now in a corner in a cluster of leaves or down in a decorative tree stump. He won't respond very well to stimulus and tries to hide away - what really got to me is that he usually greets me when I come home from work, frantically swimming back and forth when he hears me call out to him - - and now he's just like he was when I first brought him home.
He is currently in a 10 gallon, heated and filtered tank, with weekly siphoning of gravel and new clean, conditioned water added. Decorations in the tank are rinsed, and filter is rinsed out weekly on the same day of siphoning. I currently have no way of testing the water for ammonia - I can't seem to find a liquid ammonia testing kit ANYWHERE.
Link is attached for pictures of him and his (from what I can tell) swollen belly. I'm not sure what I can do. I think he may be constipated, but I don't know if anyone has seen early symptoms of some kind of illness from pictures like these. Any help would be greatly appreciated! Thanks so much, I'm just worried sick about my lil guy...
