i just picked up a juvie pike sold as a red pike. but it looks identical to yours. i figured it wasn't a red and i'd just grow it up and see what it got.
Not positive on species but definitely not a Johanna IMO. They were also sold as black lined pike at my job. Don't worry Chaitika give them a week or two to adjust they will be cruising that tank like reef sharks. Very awesome species of Pike good luck
I had 6 of those last year. Two got killed by other in the group and the other 4 were sold off. I believe they are sp. Venezuela. Or at least they grew up to look that way.
