Well, lots has happened. I started out with three fish (2 rosy barbs and one giant danio), and now have five fish(2 rosy barbs, one zebra danio, 2 otos). BUT...
I got the tank with 2 rosy barbs and one giant danio. I added two zebra danios from another tank I had. Everyone got along swimmingly. 5 fish total.
Then I added four zebra danios and two otos from the LFS. The danios were pretty small. So, 11 fish total. Everyone got along for about 10 days or so, then every day a zebra danio would be found floating. One time I only found half the fish! When the carnage finished, all four new zebra danios had died plus one of the older zebra danios. Leaving me with 6 fishies. The otos were just fine. They hid alot.
THEN, to top it off. we left on a 3-day vacation and when we came back we couldnt' find the big giant danio. The booger had somehow jumped out of the tiny space around the filter and died. Down to 5 fish. Though those 5 seemed much happier. We saw more of the otos.
Now I'm going to add more rosy barbs. See my schooling question in a separate post!
