If he hasn't gotten rid of the coccidia ask for toltrazuril next time. My boy just got over coccidia. I did 3 doses of toltrazuril 3 days in a row, then retest after a week.
Yes, he
black bearded for a couple of days too, but was fine once he was off the meds. I also gave him probiotics. (I ended up having to use coconut yogurt because it was taking too long for the probiotics to come in and no stores had soy yogurt).
It's also very important to keep the enclosure very clean while dealing with coccidia. Don't leave any feeders in the terrarium, use paper towels and replace everything and do a thorough clean immediately after he poops. Keep all decorations to a minimum, and clean his basking rocks too.
I couldn't handle cleaning with ammonia, so I used a clothes steamer to clean his terrarium. And boiling water to clean his basking rocks.
I know this post was last week, so maybe you don't need the info anymore. But maybe it will help the next person
