I bought an oto about a month ago and in the past couple of weeks I have started to get worried. In the last week he has rarely come out of hiding. In fact I thought that he had died and that I simply did not see him because my bamboo shrimp had taken care of the body. But he is still alive but his stomach is big. Doesnt look like dropsy, but more like pregnancy. I do not know how otos have babies, via eggs or what. But that is kind of what is stomach looks like. I know that I am not over feeding. I would just like to hear any ideas as to what you all think that it could be.
