Found a pike cichlid the other day which I highly believe is a Venezuela pike cichlid. The fish is about 10" and goes for 40US$. Should I get it? If in case I get it, it will be housed in a 250gallon tank with an 84"x32" footprint. I have a few Oscars there as well asa few peacock bass all of which are over 12". Will they be okay? Are the pikes aggressive as some websites say? The very last thing I will add into my aquarium is an aggressive fish coz I got burned too many times when I buy based on impulse. I observed him in the store for about 15 minutes today and he seemed to have pushed a 7" frontosa aside. What do you guys think?
