What now?
I finished cycling my 30 gallon over a month back and added four otos. That made only eight fish in the whole tank. They were doing fine until this week, when one oto disappeared and another got very sick and then died. I've been checking levels and all that and other than a small nitrite spike which is fixed now, everything is fine. Out of my two otos left, one was dead in the tank this morning.
Why?
Ugh.
