My bkack moor sits at the bottom of the tank

[latvian]

Hello,

I have one black moor in a 54 liter's tank. I had the black moor for 4 weeks now and it was very active before but it has been sitting at the bottom lf the tank, most of the time, the past two days.

The tank is fully cycled I think and has been running for 6+ months. I do weekly 40-50% water changes. The last water changed was last Saturday. I tested the water for ammonia, no2/no3 this morning and everything seem relatively low. I am attachibg two pictures of the ammonia test and the no2/no3 tests.

Any help would be highly appreciated...
