Copper rasbora - you might look at
T hengeli (again smaller & look stunning in planted tanks) as well as
T heteromorpha (the purple morph is quite stunning) - with these rasboras, select more males than females if you want brighter color, but include some female for the males to display & natter over ... these spawn easily
Neons - consider the
green neon for it's smaller size, very nice color & likely overall better health, rather than
P innesi
Glow light - some of the aquarium traded lines are considerably larger than expected (I always wonder about hormone use, also cross bred (jumbled) lines)
Look for quality fish that have nicely conformed bodies, & proper shape for the species, also note any deformed fish in the groups (usually from poor water quality or inbreeding, though the latter generally shows in conformation & non-breed-standard shape), expect fish to display subdued colors on the shop tanks (again some of the very bright fish will have been fed color enhancers or hormone use).
Buying juveniles is usually cheaper & fish age is obvious (stunted fish general have overly large eyes, poor conformation)
Fins should be clear & generally without ragged edges or tears, respiration neither too fast not too slow, fish should appear bright & active.
(apologies for reiterating details you likely already know).
I'd begin with the otos & SAE (juvenile fish can be very small & slender) & one group of tetras - maybe the rasboras as they tend to be quite sturdy & less costly - also if you want shrimp, they should be added sooner so as to establish before adding in the tetras ... I've not seen rasbora go for shrimp with the same dedication shown by tetras
If you want to have 10 of each fish group, you may need to remove the SAE as they mature but they mature fairly slowly (compared to your other fish of interest) so you'll have lots of time to reflect.
I'd time the fish acquisitions at 2 - 4 week intervals as this allows time for each addition to acclimate to your tank etc (stress significantly suppresses fish immune system)
Note that 10 otos + 10 SAE would not be supported by tank algae - at least not in any amounts you'd want in your tank ... likely 4-5 otos & 1 SAE would be sufficient algae crew (except I hate to suggest keeping fish in singles) & you'd not need to worry about removing the SAE as it matures
I've changed it to SAE to avoid confusion. Alto would I be
