Hello guys, I have been keeping these shrimps in my mini-tank for a little less than a year. Many setbacks along the way but I’ve managed to pull through eventually, and it finally seemed to be all OK...until this new crisis emerged. I have attached a photo below, the bottom substrates are slowing turning dark yellow and brown each passing day. And my shrimps are becoming less active. I fear for their lives. Can anybody tell me if this is even normal? What is the action required other than starting a new tank? What did I do wrong?
I have followed the instructions previously from people of this forum and basically leave my sheimps alone, there is some Mustafa algae in the tank but it barely grows since I put it in the tank 4 months ago. All sands and rocks were purchased from local aqua shops, no live sand involved.
The Mustafa algae haven’t grown a single bit in 4 months, hor had my shrimps bred in a year, there has to be something wrong in the tank I can’t figure out.
Please help me thanks!
