In two days i cannot find 1 zebra otto, and 3 neons, I have looked all over but can't find them. Could it be my sucker has eaten them. I dismantled the filter and no trace,. Any ideas
How big are the Angels? What size tank? It is very possible that the Angels are the culprit as far as the Neons are concerned, and even the oto is a possibility.
If the Angels are lagre enough they could easily eat your neons (Neons are natural prey for Angels). You otto might be just hiding. I have 6 ottos in my 55 gallon and I see them about once a month. I always think they might be dead but then one day I will see a couple.
