JD's Won't Eat!

[GT3050]

My 6.5" male JD and 6" Female JD used to hang out and dig nests together, but now they just hide on opposite ends of the tank and don't eat anything. Over the 12 days or so that he hasn't eatten his colors have faded a lot and he has been growing some serious teeth! He has always had easily visible teeth, but now they are probably about 1/8" . So I'm not really sure what to do, there are no other visible signs of problems with them and all my other fish are fine

Can you give us your water perameters (ammonia, nitrite, and nitrate)?

Is there any sign of disease on them, like ick or velvet?

I would try to coax them to eat some bloodworms for now. I would also raise the temperature (slowy) up to 82F or so. I would also add 1tablespoon of salt per 10gs to the tank.
