ahh a 2'x1'x1'
I have no experience with danios, most people round here say the need LOTS of swimming room,a 2' tank may do it, it may not. I advise you wait for some one with more experience danios wise
Otherwise other fish?
Neons are fine, as would be any small tetra (with the neons and few other fish I'd be careful as depending on the sorce the maybe touchy and not like new tanks)
corydorus catfish, prefrebly ones on the smaller side considering tank size eg panda cory or brochis splendens (emerald catfish)
bristlenose or oto's
dwarf cichlid (eg a pair of rams/trio of apistogramma cacatuoide/agassizii, see above neon warning)
platies/guppies/endlers
dwarf gourami
numbers
say 6-8 small fish (neons/guppies)
3-4 corydorus
1 set of dwarf cichlids or 1 ram and 1dwarf gourami
bristle/oto
this would max out the tank pretty much, also please consider these ideas only, feel welcome to research these fish, and use that as a base to move on from, eg dont like dwarf gourami, hmmmm what else is a middle/top swimmer grows about 5cm lets go look through the
