ya i agree totally. it must be known that at anytime you can lose a fish.Xenon said:Your gonna be taking a risk putting Oscars with piranha. I didnt know enough about it back then to even know the danger. You have to walk a fine balancing the size of both fish and you can never tell if its gonna end up bad. I guess I lucked out with my arrangement. I wouldnt mix the oscars and the piranha unless you are VERY aware that you will most likely lose one or the other.
