Ok...now we go over to the pseudacanthicus. Generally larger in size and meaner in behaviour. Any fish silly enough to fight for territory with it will have a terrible experience. Spikes are everywhere on the lateral sides so do not handle with hands unless u know what u r doing. These spikes can cause massive damages if the fish should twist and turn in your hands.
A net won't be a good idea for nabbing this guy...u can guess why. No "neck-spike" visible on them. Their tails are also larger and more fan shaped rather than triangular.
One guy is a L75 i guess and the other is the L160
