I have a male crown tail that i received as a gift about 2 months ago. Everything has been fine and he seems happy up until about a week ago. He suddenly started refusing to eat. I had changed his water about 4 days before he stopped eating. I don't see anything abnormal about him and have looked back on some pictures I took of him the day i got him. He looks the same. He doesn't appear to have any of the physical symptoms of any of the sicknesses I've read about. He still floats and swims around normally. I immediately panicked and began researching what the problem could be. I was thinking that maybe he was just constipated. I had been out of town the past 2 weekends and my roommate was left to feed him. I thought maybe my roommate accidentally over fed him. And just in case it was a sickness, i bought some medicine from Petco which is made by "Aquarium Solutions" and called "Betta Revive". I moved him to a different tank and treated the water with the medicine. It tinted the water blue. Then to try and help if it is constipation, i tried feeding him some peas. I've been medicating and changing his water daily for 3 or 4 days now with no signs of improvement. I did notice he pooped a little bit yesterday while i was at work and a bit today as well. It's light colored with a little darker on the end of it. So I'm not sure if it's constipation anymore. I bought a different kind of food (flakes) but he wants nothing to do with those either. I'm at a loss at this point. I don't know what to do next or what could be wrong.
