Can someone please tell me what this is? This is my first live planted tank & the first time i've used mopani wood so i just want to rule out any sort of the dreaded algae.
Whilst inspecting the tank - i noticed this white fur like stuff (very slight, but it doesnt take much for me to worry
)- my fish are pecking at it too. Is it normal, or do i need to buy a treatment to shift it - if so can someone please point me in the right direction of removing it . thanks 
All my levels are normal, but i'm not 100% if my algae eaters been out yet since i put him in the new aquarium - which is also worrying me, i know hes alive as ive seen him move in the cave - but ive caught my fish eating his algae flakes!
Anyway heres the pics of the fur like substance
