Oh, I have not even talked to the water company. I tested myself, and others on this forum told me that was medium-high.
And alright, thanks

Look on your water company's website to see what they say. You need a number and the unit of measurement - there are about half a dozen units and fish keeping uses just 2 of them.

How bout 1 Honduran red point
In a 10 gallon tank?
There are fish suitable for this tank, but many of them need either soft or hard water and are less flexible about it than larger fish can be. That's why we need to know the hardness.

This is all the information that I could get. And that the company counts my area as hard water.

My tank is too small, at 13cm long it needs minimum of 20 gallons I'd say.

Was the information that I tested from the tank - My pH stays around 7.0, GH is around 10dGH, and KH is around 9dKH. - not enough information to work out water hardness?
These are the two you need.
Fish keeping uses two units, ppm which is the same as mg/l calcium carbonate and dH which is the same as German degrees. Fish profiles use one or other of those units.
So 225 ppm and 13 dH (to round the numbers) are the figures you need.
You have hard water, at the lower end of hard. It's too soft for those species which must have very hard water but OK for those fish which need just hard water. Unfortunately, the chili rasboras mentioned in earlier posts are soft water fish. But endlers, males only as they are smaller and don't have fry, would suit this water as would some of the Pseudomugil rainbowfish.
@Essjay , is there any place in the UK that DOESN'T have at least moderately hard water?
Well, whatever the actual size , that's the nicest looking ten gallon I've ever seen.
Yes, everywhere except the south east
The south west, the north of England, Wales and Scotland have mostly soft to very soft water. I think the midlands may have hardish water as well, and there are odd pockets of hard water elsewhere - for example Lynnzer lives quite near me but he has hard water in a small pocket surrounded by soft water.My hardness is in the middle of soft and I live in the north east of England. I was brought up in the north west and the water there is slightly softer than mine.

Alright, thanks.

I've found a place where the water doesn't even leave marks it is so soft.

I'm from the east midlands, not London. And each time I've had my water tested, for the past 10 or so years it comes up as softer than average for area at 10, not 13Yes, everywhere except the south east
The OP in this thread lives in London which is well known for having hard water with the odd pocket of softer water.
