Giant Danio Fish Behavior
I had 4 Giant Danios in my fish tank and just added 4 more Giant Danios a day ago. 7 of the 8 Danios are swimming together like schooling fish do...... I do have 1 of the fish that just hangs out in the top right corner of the tank by itself...... they all seem happy, they do all eat like crazy when I feed them. Should I be concerned about the loner fish or is it just being shy?
