Adding to the guppy tank. Recommendations?

[YellowGuppy]

I've had a happy and thriving guppy tank for a few years now, and am starting to explore some new additions. I found a couple of kuhli loaches available near me, and they have made a great addition, so now I'm wondering what else I might be able to add! Obviously I'll be watchful for stocking capacity (we rehome fry on a very regular basis; sometimes weekly!), but I'm intrigued by the concept of throwing in a couple different species to make it more of a community tank. Here are some of the species I have in mind:

• Scarlet badis
• Sparkling gourami
• Celestial pearl danios

I would love the idea of killifish as well, but I don't have a lid (nor an intention to get one), and I do want at least SOME of the guppy fry to survive!

Please let me know if you have any concerns about compatibility, or if you're aware of other species that you think might be a good fit!

What size tank?, what is the temperature?, How many fish of what species do you have?

20 gallons, about a dozen adult guppies and two kuhli loaches. Temp is in the upper 70s (76-78, maybe?) but could be adjusted a touch as needed.

Keep it at or over 75 for the loaches, So, do you ever see the loaches? I mean do they come out of hiding? I would imagine that they are stressed and not necessarily acting the best for the species, as they thrive in a school of 6 at the bare minimum, and 15 being more ideal. If you can get more, I would make it a priority.
I don't know a lot about the three species you listed other than they are not too big for the tank, hopefully someone has knowledge of there compatibility

The American/ Florida flag killi is a mid-dwelling beautiful pretty small fish. They can supposedly get a little aggressive if they get hungry. Mine never caused any problems, they did have little territory fights between themselves. They might eat some fry, but that is true of almost anything with a mouth bigger than a guppy fry.

Yes, the temp is above 75.

The kuhlis are great! They pop out occasionally throughout the day, but REALLY noodle around whenever it's feeding time.

It sounds like Florida flag fish plus guppies is a no-go: they have a reputation for fin nipping, especially with anything with flowing fins, such a guppies or bettas.
