Hi all, I'm new to these forums so I hope I'm doing this right and apologies if I'm not. I'm also new to owning fish so sorry if I ask dumb questions.
We have one black moor and one fantail goldfish. They're both acting and eating fine except I've noticed the black moor has being producing white, long, hair-like feces (the fantail is pooping normally). I've seen this about 3 times in the past few days. The stuff I've read online says either constipation, internal parasite, or bacterial infection. I've attached an image, I was hoping someone could give me their opinion and possibly advice on how to fix the problem.
