I have a 1in a half to 2 inch Pbass,he is in my tank with 2 Irredesant sharks,2 Tri color sharks and a smaller Firemouth,also a TSN cat.The fish are all about the same size(except for the TSN,wich is a little larger)The Pbass is chasing all the other fish almost non stop.I had been told that Pbass are not very aggressive,but i guess that info was wrong.My question is what can i put in with my Pbass that can stand up to it without killing the Pbass???I'd like to get another Pbass but am affraid my 1st one would quickly kill it,any ideas are greatly appreciated!!Thanks
