How long and what fish

[Bawb2u]

I know this one is pretty open-ended but I'll try anyway.
I've got two pikes, C.l. cf "Atabapo",currently app.12" and 11" (please check out my other posts for specifics about them) that I'm moving into a 180 (6'x2'x2') and was wondering about how long it might be before they outgrow that or have they already? Secondly what fish might survive with them?

no they haven't out grown you tank and i don't think they will

you could try other large cichlids with them depending on how aggressive they are would decide on what kind of cichlids to try
