Ok, so I have some guppies that had internal parasites. Unfortunately, quite a few died before I found out what it was, and more have died even since I started medicating them. I tried Parasite Clear (in the water and in a solution which I soaked their food in to feed to them directly) and a medicated food that I made myself from a dewormer. Every time, they would have brown poops during and for a little while after the medication, and then the white poops would come back shortly after the course of meds was done. Well, I finally ordered one more med thinking that the parasites were resistant to the meds I was using (couldn't find any with different active ingredients around here), but today I looked into the tank to see brown poop coming off the one guppy who had started having white poops again after the last course of meds
! I was so surprised. The other one has had brown poop for a little while now, but I was hesitant to move him into my other tank until I new that they were both cured. I also noticed some brown poop on a plant!
But, I am still hesitant to move them over because I know how bad these parasites are. On the other hand, I really need them out of my quarantine tank, and my other guppy in the 15 gallon is really lonely by himself. (Yes, I know he SHOULD be fine, but I have known this fish his entire life and he was never this stressed even when he was in terrible conditions in my brother's room. The other fish in the tank all are really healthy, so I believe that he is just lonely.) So, what would you do? They look fine, all signs point to the fact that they are healthy, but I am still worried. Thanks.
