Hello everyone,
I am going to describe my tank first!
-64 litres tank with a Interpet PF2 filter cycled for about 4 months now.
-Water temperature 25 degree celcius.
-No plants. Few decorations and plastic plants.
-Fish: 3 albino catfish, 3 guppy male and 4 females, 2 swordtail koi male and female, about 25 guppy fry (5 new today)and finally, with lots of hesitation, an addition yesterday of 3 small Otocinclus to help reduce the amount of brown algae (I know that my tank is overstock now, but I am about to start cycling a second 94 litres tank to separate my female and male guppies! ). I have noticed that my female swordtail is staying longer than normal in the bottom of the tank without moving one bit! I immediately checked again my water for ammonia as I know my tank is overstocked and I read 0.25ppm which I reduce straight by a 30% water change and ammonia remover. Other readings like Nitrite and Nitrate are fine. What is confusing is after a while standing at the bottom, she starts to swim normally again. She doesn't have any spot or anything special on her body. Now, as I am looking at her, she seems to reverse to swim sideways a bit crazy and swim normally again. My question is whether the behaviour could be normal or is she developing a disease? And if so, can I do something to help? I have never seen her doing that before so I am a bit confused!! Thanks for helping.
