Thanks for the comments everyone! Added 6 more fish yesterday:
3 more cherry barbs (2F,1M)
3 Gold Metalic Barbs.
There are now: 9 Cherry Barbs (3M,6F), 2 Otos, 3 Gold Metalic Barbs
Here's 1 pic for now. I'll take more tonight when the sun goes down and the room won't reflect so much in the glass.
^^ Current fish checking out the newcomers.
