Has anyone experience Hydras in their freshwater tanks? I just discovered this, I definitely feed my fish a good amount but practically do 20-30% water changes daily making sure vacuum food and waste. I’m thinking the cause might be my lights. They’re on a timer but it doesn’t officially go off till 1am (lowest blue setting available and I can’t change the turn off time).
Any recommendations on how to treat this?
