Design The Tank

[Davidiator]

I wouldn't recommend the red tail shark with fish with long flowy fins like the angel or betta. The sharks are notorious fin-nippers.
I'd also go for some taller-bodied tetras than neons, as the angels can snack on slim-bodied tetras when fully grown. Serpae, von rio (flame), emperor, would be some good choices.
I wouldn't include the betta personally, they come from small rice paddies in asia with not much water movement, and in a big 150 with flowing water I feel it would either be lost, or pushed around. If you really like them, I'd set up a little 5 gallon for one, easy to do.
The angels, in a tank this size a group of 10 would be good

Could i do:

Angelfish x20
Male Cockatoo Dwarf Cichlid x1
Female Cockatoo Dwarf Cichlid x3
Male Bristlenose Pleco x1
Female Bristlenose Pleco x2
Congo Tetra x 7
Neon Tetra (i know they eventually will have to go) x 20

Dude pump the brakes and enjoy the fish in your tank allready.

Aro outgrows the tank and the BGK never comes out unless lights are off in house and tank I then have to use night vision on my camera

What about geo brasiliensis pair with gold nugget pleco and adinoacara metae group.

Could I do a GT community?
What fish would go with them?

You should’ve never bought a aro then. Knife fish are nocturnal it doesn’t surprise me that he hides that’s what they do. A impulse buy will always result in problems down the road. You seem to be a smart young man, but asking people for advice and then ignoring it because you don’t like the answers will almost always end in failure. Slow down a bit and enjoy what you allready have. No one here can tell you what you are going to want in your tank that’s up to you everybody’s preferences are different just use common sense.

Bit heavy on the angelfish, I'd go for like 12. The neons, not sure why you would waste your money to have them for a short period of time.

About the "gt community", you could easily do a pair of GT's. Maybe a small harem, 1m 2-3f, something like that. I don't have experience with a setup like that. But fish that would work with the GT's, would be plecos, tetras like the congos you mention, and oddball SA characins, that's what I'd do with them. Wouldn't push it with more cichlids. Pinktail chalceus, silver dollar species, would be a couple good ideas.
By the way, I think re-homing the aro and bgk is the right move.

Ignoring their advice?
If I was ignoring it i would not be getting rid of it.
Yes i did impulse buy the BGK (not the aro i was told by multiple people it could live in a 150 for its entire life)

i always wanted a community tank and i think that is what i am going to do.

so could i do 2 GTs
and the 3 bristlenose plecos
and like a ton of congos?

also if i got rid of the neons and congos could i do the angels?

Yes that stocking would be fine, I'd say go for like 20 congos max. The congos get big.
About the green terror and angels, I would probably not try it, just because the GT may get aggressive with them and rip their trailing fins. I think angels should really be kept with less aggressive, smaller, non-nippy fish. You could probably do some other smaller SA cichlids with the GT's, cupido comes to mind. But it would be dependent on how your GT's behaved.
