So, I've had Scooter, my crowntail Betta for around 9 months. He was a fully grown store-bought betta, so I'm sure he was already a year or so old. Scooter is usually a very active Betta, meaning he swims around quite a bit. But the last week or so, he's starting hiding in his cave all day and only comes out when it's feeding time. Also, he tends to lay at the bottom a lot in awkward positions. And there have been a few days where he hasn't seemed interested in the food. Scooter's tank has been extremely stable over his life with us (he's my wife's fish! that I take care of). Could he be coming to the end of his natural life? Everything else about him looks normal. I don't see anything out of the ordinary with his body or anything. All info is in my profile.
