Anyone have Goldenwonder Killifish?

I have two which appear to be one male and one female. Received as a gift and moved from my community tank because I read they can eat small fish and I decided to add in some tiny ember tetras. I’m concerned about whether I should reintroduce them or just keep them separate. They’re in my 10g hospital tank right now. Larger one is maybe 1.5” so I feel like it’s enough space until I figure out what I’m going to do with them.

I've had them in the past...they like to jump out of my 55 gallon for some reason so I just stopped getting them.
My last one got to around 2.5 or 3in and never tried to nip or eat at smaller fish,pretty cool top dwelling fish,I'd throw em back in the community and just let them be.
I never had any issues that you are describing but I may be the exception and not the rule.
If your concerned about that then just up the stock on your tetras to denture them from trying but I doubt they will

Awesome thank you!

 

It usually just depends on their temperament but I've found that they don't eat the smaller guys!

 

Don’t know if they eat smaller fish, but they are fabulous at disposing of large spiders

 

Mine was extremely predatory to anything it could fit in it's mouth. We named her Casey Anthony for the amount of baby fish she murdered. And yea they jump. Even if your tank is "mostly" covered. We found C.A dried out behind the dresser. A 1 inch gap around the HOB did her in. (Pretty sure "she" was a male but that's irrelevant).
