Can my tanks fit my fish or should i move some out?

[Aerolite]

i have a 15 - 20 gallon tank and it has 6 cardinal tetras, 1 betta (planning to put females with him), 2 kuhli loaches, 4 lemon tetras, a guppy (want to put females with him soon) and a white platy (moving him out anyway bc he was sold as a dif species so we putting him in the community tank)

so can my tank support these fish or should i get another and split them up?

They seem pretty happy but i just want to know if its going to be a healthy tank?

Assuming you have adequate filtration and keep up with water changes, from a bioload PoV you are fine. I wouldnt go out and buy a ton of extra fish, but you arent overstocked.

There are some issues with compatibility and what is generally considered to be a suitable number of social fish to keep together, but if you arent seeing any signs of stress or aggression between fish, then again, you are fine. Something to keep an eye on though.
