My german blue rams laid their second set of eggs yesterday! (I'm very excited and hope they survive)! Before laying the eggs, I noticed the female turning grey in the head area and her poo is white and stringy. She laid eggs anyways, but doesn't seem to have much interest in them, and the male is the one fanning and watching over the eggs. Today, I noticed the male now has white stringy poo also. I do feed them a blood worm treat every day (along with their flake dinner and veggie tab nighttime snack), but I'm fearful it's internal parasites. My ammonia and nitrites are 0. Nitrates are 5-10. I did a water change yesterday. I use an RO/tap mix for softer water. No recent additions have been made, and the tank has no plants. Can anyone tell me if white stringy poo could just be due to the blood worms? I do have metro food (from a previous issue). If I begin them on the food, will it affect the eggs? Does the females head turning grey mean anything? The pic is before she laid eggs. Her stomach is flat on the sides again, but her white thing still sticks out
