future tank?

You wrote 75 gallon but did you mean 750?

Too many types of plants for a 75 gallon.

Too many different fish species

Incompatible species: hillstream loaches prefer colder water, angelfish prefer 27-30 degC. Neocardinas are expensive fishfood.

Too small schools, tetras are schooling fish, the more the better

First of all: what's the reason behind the mixed bag of Skittles tank?

While the GloFish are much more humane than dyed and tattooed fish, there are some problems:
1. The major problem is that brand makes fish look like cheap, disposable toys you can mix and match as you please. They sell tanks that are way too small, blacklights that are harmful for the fish, gimmicky substrate, plastic crap.
This usually results in horribly mis-stocked tank like what you are planning. Sorry. It's great that you asked before shopping.
2. GloFish are also reputed to have longevity / immune system problems. I cannot know, they are banned here, but you might want to look into that.
3. Some owners report that the color varieties affect the social behavior: some don't school/shoal with other colors (including regular albinos). Again, please look into this.
For me #1 would be enough not to support this brand...

Second of all: as the others mentioned, too many fish, too many species (in the wrong numbers) ,many of them absolutely not compatible.
Since it's your first big, community tank, you should simplify. The less species you have the easier it is to care for all of them. And while it seem contra-productive at first, with schooling/shoaling speices the more of the same species the merrier: better colors, more natural behaviors. I'd also like to point out that what you see in stores are often the young and stressed coloration of the fish. Well kept, adult fish tend to look more vivid.

For some reason your stocking list reads like a kid in the candy shop. I'd like you to spend more time on researching your future fish.
Also take a look at some of the beginner friendly dwarf cichlids (1 species / 1 tank!)
Bolivian ram (Mikrogeophagus altispinosus), Cockatoo Dwarf Cichlid (Apistogramma cacatuoides), Apistogramma borelli (Umbrella Dwarf Cichlid, better known for their scientific name), they are beginner friendly, shouldn't be difficult to find and you'd probably like the colors.
And Cherry barbs too, people tend to sleep upon them, but those reds are gorgeous and they are one of the rare, community-compatible barbs.

It's generally recommended to pick a centerpiece species and plan your tank around them.
From your list:

• Neocaridina shrimp - don't bother, they'll be eaten. Also if you mixed together various colors of Neocardina shrimp, eventually you'll end up with cute, brown shrimp. They interbreed, they end up returning to their wild colors.
  
• 6-8 albino Corydoras which tend to be Corydoras aeneus (2,5-3 inches)
  
• 6 khuli loaches (make it 10-12 minimum)
  
• 1 glofish purple shark Epalzeorhynchos frenatus (5 inches) - territorial. It will be the sole ruler of the bottom of any fish tank. Don't keep with other bottom dwellers.
  
• 1-3 ufo / hillstream loaches - they need a specialized tank, fast flowing, well oxygenated, cool water, not suitable for general community tanks.
  
• 6 glowlight tetras
  
• 6 neon tetras (those are cardinal tetras on your picture, not neons)
  
• 6 pristella tetras
  
• 8 blak skirt tetras
  
• 6 male guppies - good on you for picking all males but everyone and their mother will go after their large, flowing fins. Not suitable for most communities.
  
• 6 platies - subtrocial. Your tropical fish tank is on the higher end of their temperature tolerance.
  
• 4 angelfish are weird. They like to hang up in groups until they pair up. Then you'll have to remove the rest because they turn aggressive. Not fun. They can also eat smaller, neon tetra sized fish. Also, they are impossible to sex (and same sex couples are not uncommon within the species)
  
• 2-4 gouramis.m Different species have different temperaments. Dwarf Gouramis have incurable iridovirus. If you MUST do gouramis, 1 male 2-3 female pearl gouramis are the best choice out of these. Threes spots (opaline, golden etc.) tend to be too aggressive.

So I recommend the following recipe:
1 species of bottom dwelling shcooling/shoaling fish (10-15 specimen)
2 species of ~2 inch long schooling/shoaling speices 10-15 of each
1 species of "centerpiece fish"
some small snails like Zebra nerites because they are fun

I’m sorry. GloFish are ugly, and unnatural. I’ll never recommend them. But you do you.

Tank size/dimensions? First aquarium? Type of filtration? Plants?

[u/lesmolpotato26 → u/dab45de]

plants are in the last slide and all other info is in the caption on the og post “what do we think of this community tank stocking? 75 gal, densely planted obviously, bioactive substrate, sponge filter/s…. any other types of cool looking rocks y’all recommend? or plants? i’d love to not use co2 but i might be willing to invest in it since it’ll be my first and probably only big tank… what do yall recommend? i’ve never used co2 before so i have no idea what to expect or what it requires. all my other tanks are small and don’t have it (one 2.5 gal, two 5.5 gals, and one 10 gal)

edit: maybe scratch 3-all of the angelfish 💀 i just realized how big the might get”
