Are my cories ok?

Shekoi

Trying to start up again
I was looking closely at my cories last night and noticed that their barbals are very short, look stunted, some hardly seem to have any at all.
haven't really noticed this before so don't know if always been like that or not.

i've got 9
had 5 juilli for over a year now
2 juilli for around 4 months
and 2 sterbai for a week.
the substrate is small river gravel and sand. no sharpe objects.

i feed them every night when the lights go out, with algae waffers, and cory pellets. they also clean up after the other fish have been feed.
Could they have been damaged by other fish?
what else could be the problem? - other then this they look and act health :cool: y
 
What subtrate do you have?

They really need a fine sand as their barbels are very senstive.
 
someone posted a reference to an article saying that substrate doesnt really matter when it comes to this, its mostly water conditions, so you should test your water
