Are there any top dwelling shrimp safe fish fit for a 5.2g tank?

Chili or phoenix rasboras are good. I used to have some. Pretty cool little fish.

Do you have a lid? Pygmy Hatchetfish might work. If you have any floating plants, some pencilfish might also hang near the top. Other than that, smaller killifish are good but will eat baby shrimp. I have some Amber Fin Lampeye Killies in my African nano tank and they barely move from the surface.

Something I don't see very often are blackfin neon rasboras. I used to have a few in a 5 gal and they stay up on the surface and are really pretty little fish.

those do look nice.

@psalm18.2 , I kept a group of Emerald Eye Rasboras* that were awesome too. They grew to about an inch long an stayed at the top two or three inches of my tank pretty much 24-7. Pics don't really do them justice because they're not that colorful, but they have bright, jewel green eyes that sparkle and silver bodies that shine like a school of sardines when the light hits them right. I had a group of 15 and they stayed in a tight group, about the size of two D batteries, end to end.

*not to be confused with Emerald Dwarf Rasboras, which stay lower in the tank
I keep clown killifish in my 5.6 gallon which has 18 inches of swimming length. I've also kept Norman's lampeye & Scheele's lampeye killifish. (Lampeyes are larger than clowns)

I had a single wrestling halfbeak in there for a time which wasn't incredibly active and seemed comfortable in that space as well.

Make sure you have a lid

The blackfin have a similar sparkle as the emerald eye, it's just through the body. Love those little fish!

And all these fish are shrimp safe?

Look up Pseudomugil Furcatus Pseudomugil Gertrudae,Pseudomugil Gertrudae AruII, or threadfin rainbows (Iriatherina Werneri) Both smaller fish that could do well in a smaller tank.

I have, they eat shrimp.

Gertrude's rainbowfish are really active & zippy, not sure they'd be a good fit for 5 gallons.

Clown & lampeye killifish won't bother adult shrimp in my experience. I currently have a breeding population of cherry shrimp in with my clown killis.

Halfbeaks are feisty though, not sure I'd trust them with shrimp. I wasn't keeping any shrimp when I had one.

Most omnivore, will try to eat anything that can fit in its mouth. I currently quarantined 6 cpd from my shrimp tank when i saw them hunting shrimplet. I didn't believe it until i saw one of them snatched a shrimplet from aquarium glass and eat them. Well, that's the last shrimplets they're going to eat >:)
I love the clown killi fish photos. But the sites say minimum 20g tank.

Seems like I'm going to try and find some clowns.

I have some clown killifish in a 5g. You need a good cover cause they are jumpers. Lost some that way. They won't eat adult shrimp, but will eat babies for sure.
