Hello painter...

There are several: Platys, Danios, Female Guppies, White Clouds, Rasboras and Barbs likely top this list.

If you are doing fish-in cycling, it's best to do it with fish you intend to have long term. I absolutely love zebra danios, and they are really hardy so you can cycle your tank with them and keep them afterwards.

Black Skirt Tetras. No contest. Super hardy.

I agree, Black Skirt Tetras. I cycled two tanks using them and I didn't lose any.

I use feeder goldfish, them rehome to one of my ponds when the tank is cycled. Although I take care to do lots of WC's and not over feed.

I've known lots of people to do this.

I used pricilla tetras to cycle my first tank, then filter media after that. I wasn't good at my first attempt at cycling, and those poor fish probably should've died a few times. They even survived an ich outbreak that killed everything else in the tank. They were true survivors. They're no longer with us, as that was a few years ago. Each one eventually passed on with no damage and in good fully cycled tanks, so I'm pretty sure it was age.

I still think danios...

Why only female guppies? Just because they're not pretty like males doesn't mean they should have to go through a life risking experience like a cycle.

I wouldn't recommend cycling with any fish, but if I had to I would say zebra danios.

Female guppies are generally hardier.
