Breeding convict tankmates

[Crew]

Ive got a 46 gallon tank and I was planning on using it for the purpose of breeding these lovelies. My question is, is there a fish that I could include in that tank that could coexist with these aggressive fish? As well as having the potential to possibly eat a percentage of the fry?
I've done research and so far it's all been a 'no' apart from one account of a large Raphael catfish living with them.
Any input?
Thanks in advance.
Crew.
