Are these a more aggressive or more passive species and cooler or warmer waters ? My limited research suggest they would want 80ish temp based on the river water temp; but tom's website has 78 in one location and 75 in another. Nothing on aggression; he mentioned it similar to cockatoo and nijjensi both which can be aggressive/territorial but not sure if this is physical similar or behavioral similar. I have 3 pairs of wc arriving and they will go into a 100 gallon established aquarium with some hatchet fishes. Anyway just i guess i can tweak things before they arrive if they turn out to be hyper aggressive though once in the aquarium it will be hard to catch them since it has a huge amount of overlapping hardscape.
