Can you tell us what the problem is, as the picture isn't very obvious.

You still haven't said what the issue is.

The problem begun with a white spot in fish's back.I have an aquarium (60lt), where there are 4 sterbais, two males and two females. Today, the second male sterbai has presented a bubble,too. Water's parameters: PH 7, KH 4, GH 3, Temperature 25.
Could you please identify what the problem is? And if so, could you please tell what is the therapy?
Below I ttache photo where you can see that the right sterbai is full of bubbles.
If the photo is not clear enough the path to see the picture is

Hi,
I google around n found this.

Gas bubble disease

Gas Bubble Disease is caused by a sudden dramatic change in gas pressure in the aquarium. This can happen by changing too much water at one time or by adding cold water to the fish tank. Gas bubbles form in the fins and skin of the fish. The bubbles look like blisters and are very easy to see. The skin will crackle if you run your finger across it. If not treated in time, gas bubbles in the bloodstream will kill the fish. The treatment is to add alot of aeration to the aquarium. Lights should be left off to minimize stress. If you see alot of bubbles that have already popped, consider adding a general antibiotic to guard against secondary infection

Gas Bubble Disease is unlikely unless it's closely connected to a water-change where bubbles appear on the surfaces in the tank (e.g. on the glass). This would indicate that the water had extra levels of gas that was dissolved due to the pressure in the water-pipe.

I'd suggest that your fish is sufferring from some sort of fungal or bacterial infection.

Do a 40-50% water change (with same temp water as in the tank and a good dechlorinator added to the water), and then medicate with a generic antifungal/antibacterial medication. Read the instructions on the medicine, and if says something like "use half doze for catfish", you should do that.

In the beggining i had an aquarium that was full planted and within it there were four corys sterbai, two ancistrus sp3, three dwarf gourami and some apple snails.CO2 bottle and a filter EHEIN 2213. PH was 6.8.
then I made a bigger aquarium and i transfered everything from the small to the bigger one apart from the 4 sterbai and the filter.
After transferring all these things from the one aquarium to the other PH came up to 8.0
Then the first fish appeared a white spot, like a skratch, and after that it become like the way it is ib the photo. The only thing done after the appearance of the spot was a water change (30%) with a colder water, so as to make them breed.
My only doubt is that the white spot might be on the fish, before transferring all these things from the one aquarium to the other (the small aquarium was too planted and i may not see the pot earlier).

Difficult to be sure but it appears to be Saprolegnia,
a fungal disease secondary to the white spot infestation. Sometimes it results from the damaged skin being left open for such infections.

Treatment for Saprolegnia is straight forward. Consult any of your favorite reference texts.

i had twi therapies.
first with melafix and primafix for 1 week
and second with furan 2 and general cure but i have not result.

If it is fungus I have had good results using methylene blue and one tablespoon of rock salt/gallon in a hospital tank but there are many ways to treat it.

I have never been able to see where Pima or Melafix work all that well but that is just me.
