Differences In Behaviour

[Cazgar]

I have Hasborus, sanchesi & peppered corys
The peppers & sanchesi are very active, always whizzing about, rooting in the sand, but the hasborus are much quieter.
They only really get active when I put food in, the rest of the time I barely see them.
Anyone noticed the same?

how many of each do you have. maybe there isnt enough in the group and they are too shy to come out

I have 6 of each, not all in the same tank
