ok after looking closely at my plants i noticed they all have very fine hair like algae that is a light green growing on their leaves - is this hair algae? what eats it? i have like 4 or 5 ottos but i dont think they touch it neither does my sae (prob a false sae) - i'm guessing an army of amano shrimp would devour it but they are out of the question at $2.50 a shrimp in my area plus my fish will eat them - what else can i go with?
