Hello, again. I really appreciate everyone's wisdom on this topic. Since I last posted, I lost my 29 gallon tropical freshwater aquarium to a sudden leak. ? Thankfully, I was able to save and rehome all the fish. But, that means my 7 gallon shrimp tank received an upgrade wrt live plants and gravel. I was hoping that would inspire some mating behavior, but I actually witnessed a female discharging what must be unfertilized eggs just this evening. The male shrimp (I thought I had two, but now I'm questioning the other's sex after some weeks) is not doing his job and I can't figure out why. I had to siphon out 50% of the water to move it from it's prior location beneath the 29 gallon. I have not performed another water change in the nearly 3 weeks since the leak happened. I check the parameters in the 7 gallon once a week and ammonia, nitrate, and nitrite are 0ppm. Temp remains at a steady 72 degrees. The shrimp are as active as ever but that male is unexcited by a tank full of females. No clue what to do next.?
