Latest addition to my tank

Yesterday I bought the latest addition to my aquarium. I got 10 Khuli loaches. They hide a lot, like is their nature as they are nocturnal animals but as far as I can see are adapting well. They are the second type of fish in the tank now, but I already have 10 Zebra danios.

Here is a picture of the Khuli loaches while still in the bags before being let free in the tank.
