New ten gallon (cycled?), and new stock died.
So I just recently built dividers for a ten gallon tank I had to put a couple bettas in that were in bowls. The tank is divided into four sections, and I transferred over a cycled filter along with a new one which will be the permanent filter. I added two bettas first which were doing fine, then a couple days later(yesterday) I added a group(6) of neon tetras. Today all the neons were dead and the bettas were just floating at the top of the tank in corners only moving a little every 10 minutes or so. My thoughts are either the neons could have been sick and brought it to the tank, or they could have succumbed to acute poisoning from the silicone I used to secure the dividers. I made sure to get 100% silicone with nothing added for mildew resistance, so I am not sure about that. I also just transferred the bettas back to their bowls to see if they will get better with new water and their old enviroment. Whay could have happened? Their symptoms are: Lethargic, not eating, sometimes their tail end floats at a 45 degree angle. The tank parameters are: Ammonia 0, Nitrites 0, Nitrates 5, pH 7.6. Ideas of what I could try?
