yea the smaller one is like out allday aha and sleeps at night and the big one you can see in the day (not moving) then comes out when lights are out... that normal?
also what is the fish second pic down, my friend bought if for me and didnt say what it was!
The fish in the second pic from the top is a Kribensis. If the albino fish near the bottom is a cory you should keep it in a school of 6 at least, they do better in groups.
