I currently have 5 Strigata pike and 3 Lenticulata pike in my 450 gallon. I am going to add 5 more Lenticulata pike after the 13th of May. What kind of issues will I have? I already have the Strigata pike pairing up and now I just want a pair out of the Lenticulata. So far I haven't had any problems as the tank has enough other fish distractions to keep the aggression down. I am not going to keep this many Pike down the road but I am trying to get them big enough to pair up.
