Answer
Your tank is SEVERELY overstocked. It is only 15 gallons (60 liters). I would rehome all of the fish or donate them to a petstore. The ammonia will just pick them off one by one.

Angel Fish need 30 gal.
Neon's need 6+ schools.
Pleco's need a 100+ tank, 150 preferably for 2x.
Danio's need 6+ schools.

7x Kribs would need a 55g alone.

You can ask me for information but its best if you did some thorough research.
