Hi everyone. My new betta, Claude, seems to be getting a bit swollen around the belly area. I have been pre-soaking his pellets and only feeding him two per feeding, with two feedings per day, so a total of four pellets daily. He always eats what I give him and I try to keep feedings small, but lately his stomach is looking a bit larger than when I brought him home. The store he came from doesn't seem to feed the bettas often and I am wondering if the sudden increase in feedings has contributed. He is also getting a different food with higher protein than the one he had at the store. The pellets he has been getting are half and half Omega One betta buffet pellets and Nutrafin Max pellets.
I am posting a link to a video of him since I am not sure what is a healthy rounded shape and what is a sign of bloating. He came home three days ago so he hasn't had much time to adjust to the new diet yet. Part of the reason I am worried is that I haven't seen him poop since he came home, so that combined with the large belly seems to indicate a problem. The cup he was in when we bought him was also quite clean compared to the others, but there was a little bit of waste at the bottom. He is still very active and eating eagerly, I just don't want to shrug it off and risk it being a problem. Here is the video link, if you skip towards the end the camera shifts around to the front of the tank and he is much easier to see. Any thoughts on whether his shape looks normal or whether he is starting to bloat would be very helpful. Also is it normal for bettas to be very active when constipated or is the fact that he is swimming around so much a good sign than he is not having any trouble? Thanks so much! :)
(his belly is a white color normally. I notice that in the video this makes it look like it is more stretched out than it is. His stomach doesn't look stretched, just round. I also called the store I bought him from, they didn't know how often the bettas were fed but advised one pellet a day, so it sounds like he is in fact used to getting hardly any food.)
