Hi, I am thinking of getting a fish to add to my community tank of birchirs and ctenopoma acutirostres. Was considering a tigerfish but after seeing their aggression in some videos, I've decided I rather stay on the safe side and go for an African Pike Characin. However I'm finding it hard to differentiate them from the tigerfish and do not wish to accidentally end up with a tigerfish. Can anyone help me tell the difference or give me tips to be able to tell them apart?
