Greetings Fishlore! So, about 24 hours ago at the time of this thread's creation, I bought 3 new kuhli loaches for my band of 5 in my tank just because they were on sale, and I noticed that one of them is holding eggs. But with the eggs, she has a very concerning chest mark... She's the only kuhli out of the 8 I now have that has this mark. Is this a parasite? The kuhli is doing fine and feeding as if nothing's wrong, showing no signs of illness. She was like this when I introduced her, and I know it's a she because she is holding eggs: If the water parameters matter on a creature that was already like this from the store: pH: 7.6 Temp: 75.6 degrees Fahrenheit Ammonia: 0 ppm Nitrites: 0 ppm Nitrates: <5 ppm I would like an answer to this as soon as possible, I will take her out if it's a bacterial infection She acts like your normal, healthy kuhli, I'd like to make that clear, she's already accepting bloodworms and algae wafers.
