    Endli bichir has white threads stuck on mouth

    Is it food? Is it worms? Injury? Appeared overnight. Bichir is eating and behaving normally. Water change weekly. Had him a little over a year since baby, he is now 13 inches. See photo attached. P.S. I grow out algae for sides and back of tank so it's not neglected and dirty.
