Is this an internal parasite?

[Sand.man]

Hi,

I just bought a new clown yesterday, and this morning, it showed a long string of poop hanging from him. After he released it, there was also a thicker, white end to it, as seen in the picture.

I fed him after I saw that, and he seemed to be eating fine, but I would like to start treatment right away.

Is this internal parasite?

I was going to start treatment of prazipro today, should I continue with my plan? or is there a different treatment that I should administer, considering what I have just discovered?

I have attached a picture, I hope you all can see it:

Any help would be greatly appreciated!

Also, for prazipro treatment, is using "ultimate" or chlor-am/stress-x combo necessary? as per the recommendation of the bottle? or will it be fine to go without those things?

Thanks a lot for any input,

Cheers.

Well I just medicated with prazipro, and used prime along with it.

A quick search showed that prime and prazipro should not conflict with each other, so hopefully things will work out.
