Questions about normal behaviour of Otos!

I've heard drip acclimation works best when introducing to the new tank.

Drip acclimation? As in drop by drop? You don't need to do anything that spectactular. You should give them a long acclimation period, however. I left the bag in the water and swapped 5 syringefuls (there was one that came with my test kit) of tank water for the bag water every 10 minutes for about an hour or so. Worked pretty well.

But, no matter what you do, it's pretty much hit or miss. They're either going to be in good enough condition to hack it in your tank or not. If they're already too far gone and you just can't really tell yet, no amount of acclimation will help them.
 
Do you guys think I should go for Round 3 of water changes, or leave it alone and see where it's at tomorrow? I'm thinking it's still at .10 to .15 ppm ammonia. (No NitrIte though.)

Yeah, you might want to go ahead and do it. .10-.15ppm ammonia isn't all that bad but you really should get it as close to zero as you can, especially as the end of the day draws near. You don't need that little amount of ammonia building up to something bigger by the time morning. Try and get it as close to 0 as you can before you call it a night. Also, try doing just 50% water changes. Changing all or most of the water in the tank isn't going to really help your cycle all that much, either.

I always thought an hour was too long. Water condition and depleting oxygen is what my LFS (a VERY good one) told me. Maybe I have been over cautious.
 
Well in this case... I had told the seller that I had an hour drive. She said she'd put in extra oxygen. (Not to mention, a heck ton of water. Which I'm sure makes them happy, but almost never have I been able to float the bag and NOT have some of it escape into the tank.)

And then when I got home, and discovered that the tank wasn't absorbing the ammonia... I had to do about an hour's worth of water changes to get it back to none. During this time, the bags were placed outside the room, in a bucket, in the dark. I did check on them every so often, seemed fine.

Then they floated for temperature for probably 20-30 mins. (It just so happened my dad wanted to do a walkthrough of the new apt and it's building issues. But to be honest, it might not have been the worst - the water probably had lost some of it's warmth.)

After that, I did 1/3 cup of water (with the 2 plus cups of their water, probably not much), about 5 times before draining the bags a little. I space it a part every 5 minutes. I succeeded in about 3 more times. While preparing the net, I turned around and sure enough, the Oto bag was tipped. (@#%%@!) When I checked, one had already left. He was already sucking the side. I guess enough was enough. So I let netted out the other Oto. The gourami and neons I continued acclimating for 15 more minutes, before netting them and letting them out.

I use as little light as I can get away with, which is pretty much the outside hall light, and little spot lamp. No direct lighting. (Considering that the bathroom is painted dark blue... light doesn't bounce around much.)

Anyway, I would have liked the otos to take the 30 mins of temp acclimating, plus an hour of water in the bag acclimating... but it ended up being 15 minutes short. As far as I know, it didn't bother them any. The next morning, I counted both of them, munching away...
 
I ordered 6 ottos from my lfs. they accidentally sold 4 of them, so I started with two. I never say them. they hid all the time, except in early evening with lights right down. Even when I did see them, they were never together.

Then 2 weeks later the other 4 replacement ottos arrived. I added them - all of a sudden I had 6 crazy friendly ottos. they swim like crazy things all day - even in the light - and are growing fast. They hunt down algae patches together and just play like children on red cordial.

I am convinced now they really really do need a group of friends. 2 ottos are just not happy together - they need more.

Yeah, even when hiding my group of otos are together. They all just hang out under the lean-to of petrified wood in one side of my tank. Pretty neat.
