Hello
I have in my tank about 10 Rasbora Heteromorpha. I just fed them and when they went to the surface to eat it looked like they were knocked down. So now I have like 6 fish on their side/ floating in the tank (still living). I've seen this before with one of them and he always survived. What causes this strange behaviour?
I know this sounds funny and strange but I'm not making this up lol
Could it be the high CO2 in the tank and high O2 outside? So when they eat they suddenly inhale lot's of O2?
Best,
Gilles
