Hi folks! I've experienced one of the strangest things in this hobby..my colony of hairy mushroom all of a sudden started dying, looks to me that something has been grabing a bite out of them during the night. Does any fish do this at all? Maybe a shrimp? Here are some pic of what I've found this happened in a period of 2 weeks from full healthy mushrooms to basically none. If anyome has experinced this in the past please advise! Thank you all in advance.
