Currently running in my very first aquarium (125 l / 33 gallons), currently on its 12th day. Nirite currently at 0,6 , waiting for the levels to peak and go down. I will add 5 ramhorn snails and 5 quilted melania next week to further support the nitrogen cycle. Once the nitrite peak has passed, I will start with placing the animals in waves, letting the water and bacteria adjust to the increased stock each time before adding the next wave in.

My current plan

1.Wave: 10 Neocardinina davidii
2.Wave: 8 Corydoras sterbai
3.Wave: 10 Cardinal Tetras
Much later: Couple of nerite snails

I was also considering ~5 amano shrimps as well as a gang of 8 galaxy rasboras, but I'm on the fence if that wouldnt overcrowd the tank.
