Hey guys, about 2 weeks ago I got a frogspawn and it's been great ever since. Today I came home from the lfs and this is what I saw. The lights were on for about 20 minutes before I got home. My sexy shrimp was on it, but it's been on it and it's been open before. I don't think I have flatworms. What is happening? Should I give it some time before I try to fix anything? Sorry, this is my first ever frogspawn and I don't know if this is common.
