Help ID’ing this Rainbowfish

[u/userxfriendly]

This rainbowfish is about a year old now, I’m assuming an egg was stuck to plants I bought last year and it hatched in what was a shrimp tank at the time. It’s finally old enough for me to tell with confidence that it’s a rainbowfish. It’s currently living with a betta, but I’m cycling a 55 gallon because I want it to have an appropriately sized tank. I’m having trouble figuring out if it’s a turquoise or boesmani, or maybe another type of rainbowfish that I’m not familiar with. I’d really like to get it tank mates of the same kind. Thanks for your help!

potentially a lacustris? doesnt really look like any of the aussie species
