Repeated regurging, concerned

[ChristinaM]

Hey folks......I'm very concerned on my corn....I will try not to miss any details.

Got Kaspar on Nov. 23rd
- was due for a feed, ate pinky on Nov. 24th
- fed again 28th, regurged (my mistake)
- fed pinky Dec.12
- fed Dec.21, regurged 23rd.
-fed Dec.28 , regurged Dec. 31

so basically he's eaten 2 pinkies since Nov.24th.

age: 4.5mos
temps: 85-88F warm side, gradient down to 70...( 10g tank )

weights:

Nov.27 6.5g
Dec.8 7.0g
Dec.15 7.5g
did not weigh again untill today due to the regurging.
Jan.1/04 6.0g

he's less now than he was when I got him, which is why I'm very concerned.

If anyone can shed some light on this I would appreciate it.
I've been very careful to not handle after feeding, etc. Everything I've read that could cause regurging, I've tried to avoid.

Only thing I can think of, is am I trying too soon after regurging and that is the reason?

Did I do permanent damage?
ack.
