How long does it take for a new betta to adapt?
I got a male HM from the local petstore a week ago. He had a traumatic beginning due to the actions of an employee, but he's been in a 3 gal tank at 79F for a week now. (He had a 100% water change two days ago. No ammonia detected.)
He eats. He sleeps (or lies still, at least). Occasionally, he poops. And that's about it.
His fins are clamped all the time. I finally got him to flare today, but his fins were still clamped. (I don't see dark or gray edges. They just don't open.) He darts to the surface, pauses, grabs a gulp of air, then darts into a hiding spot.
Is this still within a normal recovery time? I'm thinking it is -- But how long does it take for a newbie to adapt? (At what point should I start to worry and/or treat for illness?)
Would adding an oak leaf help? I don't have IAL, but I have access to oak leaves.
