I added a whole lot more oak leaves to the tank. 2 garbage bags full all total. The water is now so dark that even with a flash and 120 watts of light above the tank the pictures are incredibly dark. It's so dark now that even the bright gold color of the Cichla is becoming difficult to see... both of these pictures have been lightened for viewing purposes.
Same fish, no tanins:
I think I'll add even more leaves, a 3rd garbage bag full. Both the Hoplarchus and the Motoro rays have started to exhibit breeding behaviour. I'm really curious to see what effect the massive amounts of tanins have on the fish and their behaviour.
What do you think?
