Hi,

this should be CW116.
Very interesting to see that they even kept the different colour until they arrived in Canada.
I have seen this with white water species but usually this disappears quite fast (minutes...hours).

The aeneus group type might be CW041.

Cheers,
Karsten

These guys have been in my tank for over 3 weeks at a PH of 7.6-7.8, TDS 260-320 and temp of 76-78F. Quite the schooling cory as there 75 that swirl and go up and down the tank during the morning and late afternoon.
