helo I have a CT named Jesse, I've had him for about 3 months now.
He's in a 7.5 litre tank and i change his water once-twice a week. I check his water quality for Ph, hardness, nitrite and nitrate - and they are always ok
When i first got him, he used to spread his fins more
Nowadays he hardly does it at all - his dorsal fin and tail is always clamped, but his anal fin is often spread. He doesn't seem unhappy though, he eats well, i don't overfeed him (only 2-3 pellets a day, with 1-2 fasting days/week)
But the other thing is he's not very active. he is always hiding in his cave. he just lies in his cave, like he's sleeping, for many hours. But when i approach, and he realises i'm there, he comes swimming out to greet me and nips at water, looking for food. But if i walk away... he retreats back to his cave. Is this normal?
For comparison, my other Betta, Jack, (a veil tail) is so active, always swimming round and round. and His fins are flowing and spread. I'm looking after both my bettas the same, same feeding and water change regimen... except I've only had Jack half the amount of time I've had Jesse
Can anybody offer any advice about Jesse? I'll try and post some photos of Jesse to give you an idea
