I agree, if you were to add in a few otos, I would keep both shoal sizes to 6 individuals.This is a great selection - a variation would be to add in a few otos. Though this might impact on the school sizes.
Ok, I was curious if you had something that wasn’t anecdotal. I’ve heard they go dormant without a food source. Which is fact? I don’t know. I’m just a seeker of the truth.I haven't found a reputable source (which is a scientific paper in my opinion, but I'm sure I could), but a quick google search provides a lot of forum members stating the same thing.
Ultimately it comes down to bacteria, which has a very short generational time, needing something to feed on. Due to their short generational time, they cannot go extended periods of time without a food source, so I imagine its not more than a few days.
Now if OP wanted to give himself a little bit more time, he could continue feeding the empty tank fish food in order to introduce an ammonia source.
No I don't, but now I'm curious. I have access to hundreds of zoology and fishery, etc. scientific journals. Let me give it a quick search and get back to you.Ok, I was curious if you had something that wasn’t anecdotal. I’ve heard they go dormant without a food source. Which is fact? I don’t know.

2-3 I'd say.Would a few Oto's be about 2?
Thanks. That was quite informative, even if it was with saltwater. It indeed sounds like they could go in a partial dormant state. I heard something similar in a freshwater setting too, but can't recall from who or where.@scarface
I have found one article that contradicts what I said previously. Granted that's just one article, so take it with a grain of salt.
In a nutshell, it states that upon ammonia deprivation the ability of the bacteria to oxidize ammonia decreased by 50% in 2 weeks. And that upon reintroduction of ammonia the bacteria was back to pre-starvation efficiency within 48 hours. Or that's what I gathered from reading the abstract.

However, this study was conducted in a salt water setting, and 35 years ago...
It leaves me with a lot of questions, because the results of this study contradicts the experience of many hobbyists, because the results of this study should indicate that there should be no such thing as mini-cycles...
I'll probably do more reading on this. But not for a few days because I'm moving this weekend, and that's always chaos.
A word of caution regarding shrimp - I added 4 cherry shrimp to my tank with some tetras. One got eaten, the rest spent all their time hiding. Eventually I moved them to my 10g tank with no other fish, and they're actually relaxed enough to come out and graze. You might be able to get away with small rasboras like Chili rasboras or Celestial Pearl Danios especially if you get larger shrimp like Amanos but I wouldn't recommend tetras and cherry shrimp. Otos are also good with shrimpI know remotely about the nitrogen cycle. I learned about it mostly when finding and reading on this site. And I've had these fish for about a month and recently been suspecting my tank of being overstocked and additional reading only added to that.
With the list of fish provided jaymethy is it possible to add maybe a few shrimp as I find them interesting.
