Hello. I have a rather new aquarium set up. Its 20 litres (5-6 gallons). I cycled it for a couple of weeks, and tested the nitrates (0.05). I then did a 50% water change and bought 10 rcs, and 6 neon tetras. It all went fine, i may have overfed a bit in the beginning, but made sure to do a 20% water change every twice a week, to compliment that. 2 first weeks went fine, but then i noticed a dead shrimp. I pulled it out, did a water change, and didnt give it much thought. About 3-4 days later, and i just found a dead neon. I might suspect i have lost more shrimp, since i couldnt see them all today, but i dont know for sure. I was just wondering, is it normal to lose a couple of fish the first month of a new tank, or should i be worried? The water temperature is around 24C (75 Fahrenheit), and they dont give any signs of struggle.
Thanks in advance
