Wow, that's a massive tank! Sweet build as well.
Perhaps I will keep the silver dollars (lower the numbers a bit though, perhaps to 18 rather than 24), all of the cichlids, and the arowana. No cichla in the 900 gallon. Then, just the henleis and castexis in the tank (8 square feet per ray). Sound good?
EDIT: forgot the catfish. What about 5 ageneiosus cats and a pair or jaguar cats?
Any other suggestions for an amazon fish? I might tie a cichla tank into this with some kind of larger cat (think tig, juruense, bolt, vulture, etc).
