Tank mates help!

Morning all,
I recently got myself a 125l jewel took out the bulky filter and replaced a fluval.

Just getting it all set up and having a cycle.

I was planning on keeping tetras (few different kinds) male guppy's, and gourami (pearl ideally)

Are all these ok to get along?

The Juwel Rio might be a bit small for pearl gouramis. It's 82 cm wide (I used to have one) and the recommended minimum is 90 cm. 1 male 2 female might be OK but no more than that.

I suggest you also check the hardness of your tap water. That should be somewhere on your water company's website. You need a number and the unit of measurement as there are several they could use. And any words they use could be misleading.

Tetras are mainly soft water fish, as are gouramis. Guppies are hard water fish. However, guppies can be kept in 'middling' water as can many gouramis and tetras. Pinning down exactly how hard or soft your tap water is will tell you if can keep both, or whether you need to concentrate on one group or the other.

Thinking tetra...
You might want to consider either one large shoal of one species, or two smaller shoals of two species, to see them at their best.
If you get only a few of many species, whilst they may (or may not) shoal*, they're far less likely to school** and your community runs the risk of looking 'bitty'.

As @Essjay says, the make-up of your water is an important consideration and it is always far, far easier to match the fish to the water, than the other way around.

*Shoal meaning that they hang around together, in relatively close proximity.
**School meaning that they actually swim together, en masse, from one side of the tank to the other.
