If you've just filled the tank, it's gasses dissolved in tap water coming out. They will go away.
30 litres is very small for a cold water tank. Off the top of my head I can't think of any cold water fish suitable for a tank just 40 cm/15.7 inches across. Most cold water fish need a lot more swimming length.
There are fish which would be OK in a tropical tank, though, if you were to get a heater. Depending on how hard the water is -
Soft water - a single betta; one of the species of Boraras; perhaps ember tetras
Hard water - male endlers (no females as they get too big and have a lot of fry)
You can find your hardness by looking on your water company's website (in Liverpool it's probably United Utilities) - you need a number and the unit of measurement.
But before you go out and buy fish, you need to prepare the tank. This is called cycling and involves growing two lots of bacteria which 'eat' the fish waste.
Fish excrete ammonia which is poisonous. The first set of bacteria eat this ammonia and turn it into nitrite, which is also poisonous. The second set of bacteria 'eat' nitrite and turn it into nitrate. In a brand new tank, there are virtually none of these bacteria so we have to grow a lot more. They are slow growing bacteria so it takes a few weeks. There are bacteria products which add these bacteria but it still takes them a while to settle into the tank.
A biorb is not really suitable for live plants as those rocks on the bottom are part of the filter media and are too big for plant roots. So a plant cycle is not really an option with this tank. That leaves fishless cycling. There is a method on here which gives a step by step guide on how to do this - and a bottle of bacteria (eg Tetra Safe Start) will help things go a lot quicker.

It is possible to cycle a tank with fish - their waste provides the ammonia to feed the bacteria - but it is hard work as the water needs to be changed every day. If you really want to do this, we can help you keep the fish safe.
