Will this be to many fish?

A few things jump out at me here....
> Your tank is only a month old and likely won't stabilize for a few more months.
> You already have a fair number of fish for a relatively new 50g tank.
> I feel that long term 25-50% monthly (especially w/o living plants) is not enough to maintain high water quality with the fish that you currently have, let alone the overstocking you've suggested. Remember, there's no such thing as too much clean, fresh water.

Now it always a great debate. Every tank is different due to tank maturity, stock level, feeding amount/frequency, plants (especially fast growing floating plants), tank maintenance....
I do a 50% weekly water change on most tanks, while I do 50% 2x week on more heavily stocked and grow out tanks.

Since it seems you might be relatively new to the hobby, I offer Newer Hobbyist Primer, a collection of articles that provide a leg up in this fascinating hobby.

I’d get live plants inc floaters. Then when your tanks confirmed ok I’d get more of the fish you already have.

When i was a wee kid and water changes didn't exist; we went 4 years without a water change; then decided to do one. We put our 3 dot gourami (remember i was like 8) into a fish bowl where it died; so we could do a water change; pet shop said he likely suffocated; we decided water change was a baaaddd thing since it killed our beloved 3 dot gourami (blue gourami for modern folks).

Alas the internet changed everything and now hourly water chnages are required.
