I just did this video of them...when I turned on the room lights they were shoaled together mid level in the tank...then when i turned on the tank lights they kind of just sank to the bottom...one was swimming around, the other was kind of going in slow circles and the last just layed there...i'm kind of new to the piranha thing..so help is appreciated...do they act like this ever?
they are there for food lol, i just picked up a few of what they were eating at the lfs...i will see how the spotted raphael does though...right now its about 2-3 times the size of the rbp's
