Charles is the pro on this but keep away from feeding protein (blood worms) unless it's a carnivore plec. And especially if it's young. There's lots of veggies in Alberta. Research your diet for these guys first.
I would guess that next to screwed up PH the best way to kill young plec is to overfeed and feed the wrong diet.
Zebras are very hardy like Charles said, but for sure at 2" they are not near large enough to spawn, let alone sex easily. You could prob. vent them with a magnifying glass, which wouldn't be fun nor easy either.
If you want some pretty plecos but still carnivors stick with some other hypancistrus species, L333, L260, L411, L201, L129, L340 etc. Most of these fish you cannot get wild caught anymore as they are not allowed out of Brazil, and if they are they are very pricey indeed. Many people are spawning them though and Charles gets in some nice hypans from Columbia for a great price (L340 & L129).
Or go the other route and get some ancistrus (Bristle nose), there's tons of different one and they are much cheaper as well. Spawn super easy, etc.
