So, I left for a day and a half (around 32 hours) on Thursday and fed Finny his normal amount the very morning I left. I made sure his heater was on and that his tank was at it's usual 81F. At night, it drops down to 78F normally.
I had to turn my room heater down before I left, so his tank temperature went down to 75F, which is the coldest I think he's been (except for whatever temperature he was at the petstore, he was a gift from someone passing through there who knew I wanted a betta and a tank).
Since I got back, I slowly raised his tank temperature and he seemed happy, but I noticed he hangs around the heater alot, even though his tank is at it's usual temperature, and at night his tank goes down to the normal 78F. Basically, everything is back the way it was before I left, only how he hangs around the heater alot. Like he doesnt go to his tall plant on the opposite corner of the tank as much, if even at all.
Is this just a leftover habit do you think? He eats normally and comes to see me mostly like he used to, 1 out of 10 times he wont greet me like he did before I left. Should I give him more time before I start getting worried?
