how to tell if my rainbow shark is prego

how can i tell the sex and if my rainbow shark is prego?

I don't think there is any sexual dimorphism in rainbow sharks. Last I knew that in order to get rainbow sharks to spawn, breeders have to induce them with hormones. I'm gonna doubt that it's prego.

They just get fat by thier nature.
