Wow, this is an awesome tank. Have you looked into vermiculture to raise/sustain a group of feeder worms for your tank. There is a lot of interesting info on the web and it could definately suppliment your food for the tank, especially during the months when you won't be able to gather insects/bugs.
I thought about it... there's a BUT ! If I should count on a vermiculture for feeding my fishes, I should start at least 3 pieces of it to be efficient enough in terms of quantity... I had one when the 1,600 liters "Xingu" was on... but with "only" 7 Retroculus xinguensis one vermiculture wasn't enough...
imagine with 4 Silver arowanas, 7 Cichla kelberi, 15 Myleus schomburgkii, 3 Chalceus macrolepidotus... but that could probably be a interesting complement... I will rethink about it. thanks
