Could i have some kind of Herpes?

I always enjoy watching my fish frolic in his bowl. And the other day when i was watching him, i noticed a rash he had on what looked like his penis. I looked this rash up on the internet, and there was only information about human rashes. The verdict was herpes, and i assume its the same for humans and fish. I Thought it would be funny to put water in my mouth and try to hold him in my mouth before i found out he had herpes. Is there any possibility that i couldv'e recieved mouth herpes from him? And i put him down my pants sometimes. Could i have genital herpes/be pregnant from this 'play date'?
