Crocea Help

[Renegade]

Hey i have a 6in crocea in my 120g. I have had him for 6months + and the last 2days he will only partly open. All parameters are fine

calc. 410
alk. 11dkh
phos. 0
ph. 7.8-8.2

i am running a calcium reactor and kalk as top off.

Any suggestions or is this normal.

when i first got him i made him a shoe for his foot, which is still tightly in place.

He is only about an 1inch open with no mantle extention. He is also under 250w MH about 12 in deep

oh and my blue and gold maxima are just fine along with my derasa
