Perhaps the breeder can give you some guidance.
Other than that, water quality is super important for these fish. I'd be concerned that your 17 gallon, while may have enough room for them, especially with plenty of structure, won't have the water volume to provide stable conditions without frequent and relatively large water changes.
Meaty foods. Live foods, blood, black, white worms. maybe your culls from the shrimp tank would make a tasty treat.
Current, they like a good flow.
Caves, make sure there are multiple for each fish, so they can each find one they like.
You're good with the heat.
The rasboras and ottos should be ok, they may even be good dither fish.
