I bought a moss ball from petsmart in those little grab and go containers by the bettas. It was (to my knowledge) never kept with other fish. It's been in quarantine for 3 days now, and I picked it up to look at it, and I noticed there are some little yellow blob thingies on the outside of the moss ball... I'm not sure if this is a part of the moss ball or something else? Thanks!
