How many ember tetra in a 15UKG tank?

Pretty sure I want to go for a group of these now - the tank will house nothing but 3 oto's, possibly a handful of bee shrimp, and then a shoal of some dwarf fish. Maidenheads have loads of ember in and they look lovely in the planted tank in store, and I like them from George's nano from a while back.

They are pretty tiny, so I'm thinking a group of 20+ would be OK? Tank is filtered by a TetraTec EX600, running EI etc. etc..

I had 20, it depends on your general rule. They grow to a 1.5cm so if you say for every inch of fish you need a gallon that means you'd be a max stocking at around 26 Embers.

20 seems a good number then by the time I add the oto's and a few shrimp
