Mantle too exposed?

[DiegoSM]

Hi guys. I´m looking for a opinion 

 

What do you think, is the mantle too exposed for these clams (Crocea)? 

 

Both are showing better colors than in the LFS (More less 1 moth here in my aqua)

 

Also both shows a good new shell formation

 

Parameters:

 

pH 8.4

Ca 420 ppm

Mg 1300 ppm

Kh 8.8 dKH

NH4 and NO2 = 0

NO3 = 4

PO4 = 0.04

Temp. = 25.3 - 25.8 ºC

Dens. = 1025

Light LED = 30W right above the Clams for a 25 cm water column from surface to clam´s mantle

They look pretty good to me! No pinching or gaping. If they are putting on new growth then they are probably good to go.

They look great, its when theyre closed you should be worried. I just moved my clam and it ended up dying.
