Fish Similar to Harlequin Rasbora

[Circus]

I recently added to my school of Harlequin Rasbora and moved them into my 55 gallon tank.

When I first purchased them, I was working with limited options and not super excited. Once they settled in though I had a blast watching them. They would run around the tank and poke their noses everywhere, and play like madmen in the water flow. I think they might be one of my favorite fish so far.

I am getting my 55 stocked up now, and will be moving onto my 80 and 90s here soon, which will shuffle my tanks and fish around.

This will leave room in one of my 29 gallon tanks. The only fish I have confirmed for that tank are dwarf chain loaches and oto cats. I am looking for fish that have personality similar to my Harlequin Rasboras, but not too similar in color.
I am looking more for personality than for looks.
For tank Parameters, this is what I am working with.
Standard 29 US Gallon tank
Temperature will be set in the loaches range, so 76° to 82° F
Ph around 7.4
Hardness between 100 and 110 ppm, usually.

Rasbora espei is way cooler than the harlequin. Hardier, smaller, brighter.

all the fish in the genus trigonostigma

Check out glolight tetras, Hemigrammus erythrozonus

They tend to be a bit shy and less hardy, but I've enjoyed celestial pearl danios. If you get the tank right, their personalities can be fun to watch. Beautiful fish.

Agreed, gorgeous fish, but they are so small, I'm afraid in a 55G the OP would never see them...

I agree that espies would be a great choice for a 29g. If you want personality and "playing like madmen," check out zebra rasboras. I huge school of them is really fun to watch, plus they're fairly indestructible (though prone to inbreeding). They have fish ADHD--always zooming around and up to something.

Or 50!
I'm all about heavy stocking, lol (when filtration is adequate)

This is the problem with espe's and hengel's rasboras and even glowlight tetras, they are all more or less the same colour.

Apart from the three Paracheirodons, I can't think of another fish that it a totally different colour from harlequins

 

[Slaphppy7]

Green (false neon) tetras?

 

[Essjay]

That's one of the 3 Paracheirodons I had in mind

That reminds me - Microdevario kubotai. Smaller than harlequins and faily bland in shop tanks but definitely green once they've settled in.
