Oto help!

sounds to me like your otos just might be going hungry. The algae wafer pellets don't tend to just disappear over the course of a day. Note that otos tend to be night prowlers - so feeding just before you go to bed is more in line with their schedules. And yes, other fish like algae pellets - so it's a bit hard to tell who ate it.
Otos should have a bit of a belly - see if you can get a good look at yours - if it's concave in any way, probably just hungry. Some of my otos are extensive cleaners - constantly cleaning the tank at all hours of the day. But in my other tank, they hide - at any time I can only see two, but I know there are four in there - they must come out at night. I check their bellies every few days to make sure they're getting enough to eat. I had an outbreak of hair algae a while back as well - and lost a couple of otos in that - must be like the hair algae prevented any other algae from being accessible to them or something - they just starved. So clean your hair algae manually, and hopefully algae that otos like will take it's place.

Don't know if any of that helps, but it's what I've experienced with mine.

Curious to where this information is from. The frogs deal well with Neons from what I read prior to purchasing them, and also just from watching them.

I was actually more concerned about your frogs getting enough to eat. If you don't target feed them (with turkey baster or tweezers) theyre going to be as hungry as the otos (assuming thats whats wrong with the otos), especially since you have a group of them. I was also just stating that dwarf frogs usually do better in a species tank based on my own experience. It's really a debate though, I've seen just as many people that keep them with fish than without.

So, do whatever works for you. Clearly, though, *something* is not working. Just be sure to keep testing the water, keep up with water changes, and be sure to provide a balanced and varied diet to all your animals. Try and figure out what's going wrong.
