Can 2 jack dempseys live in a 40 gallon together?How long would they survive in it?

Can a pleco live with a oscar in a 55 gallon? What would happen if they were put together there?
 
Yes. 2 Dempseys can survive in a 40 gallon tank. Will they be happy? No. Will they be stressed out? Probably. Will their growth be stunted? Most likely yes. BARE MINIMUM of 55 gallons for 2 JDs. Bigger is much better.

Yes. A pleco can live with an oscar. You just need to keep an eye on the pleco to make sure the oscar doesn't pick on it. They tend to bully fish smaller than them.
 
Jack Dempseys would be happier in at least a 75 gallon tank, especially if you have two. If they are both males, they can each stake out a territory and have enough space not to kill each other. Or you could get a breeding pair and raise fry.

Oscars need 75 gallons at minimum as well to be happy. With a common pleco you would need to go up to a 125 because they get huge (18-24 inches). An oscar and a plec can get along just fine because there is no competition. Plecos are bottom dwellers, oscars prefer the middle.

If you can afford a big enough tank, by all means go for it. All those fish are amazingly gorgeous and its a lot of fun to watch them grow. If not, I would aim for fish that don't get as large. Happy fish keeping!
