2 of my platies have been constipated for 3 days now. To cover the diets of all my fish there is a combination of flake food, algae wafters and bloodworms. They are passing the stool eventually, aren't bloated and still active. I've tried peas, but they won't eat them. All my water levels are stable and I did a 40% water change yesterday. Is there anything else I can try? I don't want to lose my platies because of a poo!
