If it is a 15 gallon tank or less than yes.
You should only have 1 fish per gallon of water in a fish tank. I wouldn't put more than 2 or 3 Neon Tetras in a 4 gallon aquarium with 1 Betta.
many small fish such as small tetras, rasboras, smaller shrimp, guppies, platies, endlers, etc. or, you could get a betta with a small school of tetras as long as neither of them are fin nippers as their personalities vary by individual.... (the betta would love you for all the room)
You can put at least 5 neon tetras with Betta's because neon tetras need to be in a school. If you only put 1-3 neon tetras, then they will probably be eaten by the Betta because you won't have enough neon tetras to be in a school. The purpose for a school is to protect themselves from predators with a group and if you only have 1-3 neon tetras, then they will hide and get really stressed out. So, get at least 5 neon tetras and another important thing is, get a big enough tank for your Betta and neon tetra. That is, because, as you know, Betta fish are territorial and need their own territory and if the neon tetras enter their territory (if the tank is small), then the Betta will probably attack (that is only if you don't have enough neon tetras and not a big enough tank). So, it is important to get at least a 10- 15 gallon tank and get at least 5 neon tetras for 1 Betta fish. 1-3 neon tetras won't work. They will not be in a school and will be stressed out and hide from the Betta. A thing about neon tetras that is interesting and is cool is that, neon tetras bury their eggs in the gravel (Make sure to only have gravel!) if their eggs are not going to hatch. Also eat them.~Thank you, and good luck!~

Do you have any idea how big most Plecostomus sp. get? They grow into monsters (12" minimum) and your tiny 10 gallon tank won't be big enough for it by itself. If you just had the five smaller fish and the Betta you would be very close to overstocked because your 10 (nominal) gallon tank will actually only contain a maximum of around 8 or 9 gallons. Tanks are never filled to the brim and probably also have gravel on the bottom which will displace some water.
You would be very close to overstocked. I personally would get rid of the snails.
Algae Eaters, 'Mickey Mouse' fish, Platies, Cories, Tetras (Not Neon Tetras though, they will be eaten) Hope that helps!!
No, they are fighting fish. They will kill each other no matter what sex they are.
The problem will not be the tetras coexisting with the Bettas. It will be the female Betta. She will undoubtedly be killed by the male. He may well spawn her first but afterwards, if she is left in his presence he will kill her. Also if he has ova or fry to look after he will kill the tetras in defence of his young.
Well, the guppies might nip the angelfish's fins, which, in return, would cause the angelfish to chase and possibly eat them. The angelfish would terrorize the danios and tetras by chasing them. Quick side note: if you are planning on keeping a platy, I really wouldn't keep one! They're quite social fish, and they like to be in small groups. Basically, the angelfish will chase any small fish. The biggest problem you will encounter with this aquarium setup is the fight between the angelfish and the betta. I know from experience-I kept an angelfish and a betta together in a tank myself, and the betta ended up dying. The angelfish will nip the betta's fins, and the betta will nip the angelfish's. They will chase each other and bite a lot. My betta had fin rot and died because the angelfish had caused the fin rot to grow due to the fact that she had torn off all of his fins. I would definitely rethink this aquarium setup.
Surprisenly I had 2 male betta in the same 150 gal tank with other fish and had no problems. Other fish included gouramis,tetras,angels,cory cats
Betta fish, guppies, tetras.
