Not the best camera person!
Hahaha thats ok!
Looks like you have two male guppies, 3-4 neon tetras, and the two gouramies i mentioned earlier!
So from here you have the guppies and the gouramies that are both top middle/ top water column swimmers. If you could re home one gourami, ( to a friend or back to the store and i would wait until someone with more gourami experience can help you before deciding which one to keep)
After rehoming a gourami you could (ONLY if you want to have some fry (babies)) get two to three females for each male. So 4-6 females total. Only if you want to.
I would not recommend just one female by herself, the males would gang up on her and stress her out a ton
With two or three females to keep each male's attention you have a much lower risk or stressing the females out.
And again only get female guppies (normally are labeled as female in chain pet stores) if
A) the males beat each other up , or
B) you want to
From there you have the neon tetras, which are a schooling fish (i think you had 3 -4?)
If i remember correctly they are middle water column swimmers, so they have little to no competition with your guppies/gourami. I would get a few more, because sadly the pet store was wrong. Three is a "school" but not quite to the degree that the tetras need :/ , i would look into getting them a couple more friends
Edit: The water column is important because if you had a tank with a bunch of gouramies in it, they would all fight for the upper column of water space, which is where they naturally live and swim. Same goes for the tetras in the middle column and if you had a bottom dweller as well.
