dude i really liked your video! how long can those two stay in a 100 gallon tank? im considering getting one, doeas an armatus get alot bigger? can you keep the payara with an armatus?
They can stay in a 100 gallon for life if there are only like 2 or 3 I think. The armatus would need a much larger tank and I wouldn't put the 2 kinds together because of the difference in aggression and size.
