I bought two ottos and put them in my newly cycled q-tank, one died overnight. I went back and bought three more hoping two of the five would make it. Ended up with 4 out of 5 making it.
Busy little guys! I doubt they would be able to control any brown algae problems however. Mine love algae wafers.
The rock that was covered with brown algae in my q-tank would never have been cleaned off by the ottos (my obeservation only).
Two of my Nerite snails wiped out that algae in one day.
Here is a good photo of a double wammy for brown algae!
