i use ottos in my tanks they do a great job for brown algae...i have 4 in a 29 gl...i know what ottos look like and how big they get when i went to buy my last 2 i have i got them from a otto tank and at the time they looked like ottos(kinda tanish with black backs) well after a few weeks these 2 are more yellow tan type color and they got to be twice the size of the other 2 normal looking ottos....can these still be ottos or is it another type i was sold by mistake...they do eat the brown algae just as good as the other ottos...also are there any type small size fish i can get to eat hair algae
otto...maybe not
