Hey Guys,
Over the last 3 days i have noticed my fish have not been as active as normal, and have now had 3 Tetras die (2 x Rummy noses and 1 x Black phantom). I tested my water this morning and everything is fine except the nitrite levels are high (~1-2mg/L). I did a 20% water change and tested again and they are now ~0.5mg/L.
I have a 23L tank and i just introduced 2 x Clown Loaches a little over a week ago. My tank has been set up for over a year now with no problems at all once since the tank was cycled. Im just wondering what could have caused it and what I should do to fix it?
My initial though was it could be re-cycling because i added my new fish (which has never happened before when introducing new fish) but the ammonia levels are 0mg/L?
Any advice would be greatly appreciated.
Thanks heaps.
