wow two people your so good, see you still look stupid like a childish kid
A lot more than two people will tell you it's not good for goldfish and betta to live together. In fact it's even on Betta Awarness on Facebook as well. A group run by people who have been keeping betta for a long time.
And that is only the basics, as pointed out by Choc goldfish need powerful filters because they are fish with HIGH bioload, betta hate such filters. Goldfish are coldwater and betta tropical, Goldfish grow to be very large and eat betta, betta are small. Most goldfish need 30+ gallons of watter, betta only 1.
...I just wanted to know if I could add a snail or something...
If you want a snail go for mystery aka apple snails, true they get big but ramhorns, nerits, etc will breed and overpopulate quickly leading you to need assassin snails to thin down the population. They are also harder to keep under control. For a 10 gallon you only need one mystery snail and even if you decide on two they lay eggs above the water in a cluster which can easily be removed and destroyed when need be. They also have genders unlike most other snails and mystery snails are either male or female, not both.
Edit: And also if you consider shrimp don't get shrimp until after your tank has been fully cycled for 2 months +. They are very sensitive to changes in the water and die easily.
LadyVictorian ya i know there not good tank mates i actually got him when me friend was moveing around 4 years ago, she had him for only about three and was just going to give him away, but it was something to remember her buy so i took him and then i got July about a year ago and they never have had any problems, actually has's weirdly the same size he was when i got her, she said he never grew either. But for the most part middle schoolers make me made and he picked an argument when i was kindly trying to end it
