I'm curious if anyone has successfully kept angelfish with otos (otocinclus). My big concern would be that the otos don't get much bigger than neon tetras, which can become lunch. Anyone have any experience either way?
Oto's are tough cookies! They also have sharp spikes at the end of every fin making them hard to swallow! I have lost a few here and there with Angels and Otos in the same tank but I think that other issues were at hand.
I had at least 6 oto's with a large male angel, and he never bothered them. That angel died, I moved 2 others into the same tank, and no I only regularly see 1 oto.
