I dont know about the red devil but mine i fine with my jack dempsey. They problem is if the jack dempsey or red devil decide to attack the bp he won't really be able to defend himself. What size tank is it? Also do you have a backup tank?
Yes I'm going to keep it...I'm just wandering if it they would be ok for the time being the parrot I was looking at is also a juvenile...I know it depends on the fish, my red devil is very passive right now but I know that can turn any day with them and by jack dempsey is alittle aggresive but the parrot is in a tank with dempseys at the store and looks to hold its own
