I started a new 20 gallon tank about 3 weeks ago (all cycled and such) and have a mix of real and artificial plants.
But I'm having issues keeping the Rummy Nose Tetras alive. All water parameters are set specifically for rummy nose since they were what I had decided on before even setting up the tank. I finally picked up 6 RNTs and 5 Bloody Mary Shrimp. The first two days, all the tetras were looking great. Bright red noses, high contrast tails, swimming, schooling, and eating well. Then following day, one tetra began swimming in a corkscrew pattern and didn't seem to be able to straighten his body out and died a few hours later. The remaining fish (and shrimp) all still looked great. Then again the day after that, another tetra started to change his behavior. He started getting a bit left behind by the school and would hang out in a back corner of the tank, only schooling occasionally. He didn't eat anything at their morning feeding but seemed to be schooling better a few hours later. Then, within about two hours, he stopped swimming pretty much at all, and just let the current in the tank float him around until he eventually passed.
There are no visible signs of disease like spots or lumps. I know RNTs can be pretty delicate but I'm testing the water everyday and don't see anything that could causing them to die off.
Any advise would be greatly appreciated! Thank you!
