I've been contemplating this post for a while, but I feel like I need to address it, so here's the story: When I first got my Betta, he loved to explore, for the first month I had him he was zooming around his tank. He rarely stopped to rest and would always get excited if I came near his tank. He was so fun to watch and be around. After about a month or two of being in the tank, he became very lazy, not lethargic, he still got really excited when I came over, but he spent most of his day resting on plant leaves. He is a Superdelta Tail Betta, so his tail is a little heavy. But all he would do was rest. He would stay in one spot for 5 to 10 minutes, then move a few inches, sometimes more, and rest again. Sometimes he would investigate things in the sand or dash a bit and spaz out, but he just lost his activity. If I move everything in the tank and rearrange it, he will be pretty active, but not as much as he was and not for more than a day. Now he rarely moves from this one corner, but I'm giving him a break, as he has Fin Rot right now. He is still eating perfectly, and when he started becoming inactive, he showed no sign of sickness (I say this as he's sick right now). I don't know if he is bored or what, but it breaks my heart to seem him like this, he isn't the fish he used to be. His tank is 10 Gallons with plenty of decorations and plants for him to swim around and in, the current is not too strong, and the tank is now always 78ºF and the parameters are always kept at 0ppm Ammonia, 0ppm Nitrite, and 0-5ppm Nitrate. I don't know what's wrong with him if anything. Does anyone else have a Betta like this?
