My Tanks:
Day: Tinfoil Barbs hyperactive, Jack Dempseys moderatly active but mostly hide, Firemouth active and schools with the tinfoils(weird), Pictus cat SUPER HYPER ACTIVE, Senegal Bichir chills near top on plant catching stray worms that float his way, Peacock eel nowhere to be found. BGK mostly in log occasional run to his top corner looking for worms.
Night(dark): Tinfoil Barbs huddle together in corner behind large plant, Firemouth in cave, BGK & Senegal free swimming all over tank, Peacock eel nowhere to be found, Jacks apparently watch me sleep(creepy, *shudders*), Pictus Cat still SUPER HYPER ACTIVE.
Early Morning(small amount of natural light about 5:30-6:00 am) everybody appears to be resting(even ADHD Pictus), except sometimes I can catch my Peacock free swimming.
I observe at night via the light of a Nintendo DS, works pretty good.
