I have recently put in a BTA in my tank (like a week ago) and he is not

really small,

Mine can stretch out far from it's foot, so I'm trying to think what the
"small part of his body" would mean. I'd say he's doing fine. I'd
just leave him alone, and keep monitoring.

They also occasionally cycle especially after a good meal, where they
look just dreadful. Don't worry until it's foot actually lets go and it
slumps to the ground in a heap. Otherwise, it's fine and just part of
it's usual activity.

I've had two that died on me, but they didn't do much to my tank. I
wouldn't worry much.

One thing you didn't mention was current. They need a gentle bathing of
current, but not too strong either. Their tentacles should gently sway
in the current.

You may want to pick up a clown fish if you don't have one. They'll
clean and fan the anemone, and are a delight to watch.
