What tropical fish can I keep in a 35 litre tank?

I am setting up a new Arcadia Arc Tank in my bedroom. It is 35 litres and I am wondering what fish I can keep in here. How many gallons is this. Are Black Mollies ok. Please suggest small but active fish I can keep in here.

Black mollys are NOT ok, they get way to big for your tiny tank. A Siamese fighting fish (betta) would be ok. But only 1.
Or look for small staying, NOT too active fish like Boraras. You could put like 10 or so in your tank.
Keep in mind that not all small fish will fit in your tank. Neon tetras for example are small but need a school and they are very active and need more space than you can offer in your tank. They would be miserable, get sick quickly and might become agressive toward eachother in a small tank.
You could also keep mini shrimp like red cherrys/red dire or yellow fire in your tank if that is something you’re interested in.
I have redfire shrimps and boraras in my 30l tank which works well.
There is also a website for small fish, it’s in German but maybe you can look at the pictures and if you see something you like look up the name for English descriptions: http://www.minifische.de/miniTopTen.html
hope this helps a bit, good luck with your new tank.
As these tanks are open topped I would suggest male guppies as these are less likely to jump out than mollies as well as staying smaller.
You can get black guppies and the tank could house about 7 male guppies in assorted colours.
35L is not a real big tank and really im not gunna tell you what to put in it but i would recommend a pair of kribensis only 2, a male and female.
they are my favorite fish by far, each one of them has there own personality
i have had my 6 for the past 3years.
you could probably put a small catfish in there as well like a bristle nose or sumthing
anyway check em out kribensis.
