I have a female Green terror that I bred myself so she has only been in my tanks. She is now in a 75 Gallon with a male. I bought this tank maybe 3-4 months ago used, it was sitting for a pretty long time so I doubt anything was in it. Also I cleaned everything very well. For the last week maybe a bit more, she isn't eating and looked really stressed, in the beginning I thought it was because all of her kids were eaten in one night and after that the male was a bit rough rough with her but she has a rock that only her can hide behind it. I waited thinking it would pass but she is not eating at all. She now has a bit of a sunken stomach but today I saw weird white poop coming out of her. The symptoms would seem to be for sure some internal parasites but the last fish I bought that they were in contact were 5 festaes I bought maybe 8 months ago and they are all 100% fine. So I just don't know how she could've gotten something. They are now with a senegalus bichir and a brown ghost knifefish. They are with me for over a year. Would you say it is internal parasites or it could be only stress, should I take out the male ? And if it is parasites how could I treat it ? It's the first time I would have had parasites in my fish room
