I have just recently purchased a 150L tank. Originally I had a small 8L tank with 2 zebra danios and 2 white clouds.
The 150L water parameters currently sit at:
PH: 7.5
Ammonia: 0ppm
Nitrite: 0ppm
Nitrate: 5ppm
I moved the 2 zebra danios from the 8L tank into the new 150L tank. A few days later they started swimming strange. It seemed as if they were trying to swim (back fin was kicking) but they couldn't get anywhere. A few days later I found them dead, upside-down at the bottom of the tank.
I decided to purchase 6 danios from my LFS. 3 of them are definitely zebras, the other 3 are slightly more orange and I think they might be zebra longfins? 2 days later, a zebra danio was dead, upright stuck to the filter inlet. The remaining 2 zebra danios are showing the same symptoms of trying to swim, but can't move themselves. Sometimes it seems as if they are stuck in the middle and can't make it to the top of the tank, and then othertimes they are floating to the top of the tank and are struggling to stay down.
The 3 longfins? aren't showing these symptoms and seem to be swimming around the tank happily.
3 dead zebra's - same symptoms - all seem to have died with gills that looked slightly bright red.
Equipment in tank:
200W Heater - Set to 24c - Although the thermometer (other end of tank) usually reads 22-23c
Air Curtain - Sitting under gravel - Providing slightly larger air bubbles
Aqua One Canister Filter
Any help would be appreciated.
