Odd befaviour of Corys

Post by Jon_D »

About to feed the fish and noticed that 3 of my Cory shoal of 8 were actually lying on the top leaves of plants in the CT, just below the surface. Other species were swimming about as usual. Also there is plenty of surface movement so I don't think they are suffering from lack of oxygen.!. They just seemed to be resting. I haven't seen that before in the + years I've had these. The water temp is 30.5, maybe too hot?

Yes, they prefer it more like 22C, so it's a bit warm, probably cooler and more oxygen nearer the top.
Mine have been all over the tanks the last few days....

Thanks Ian, time to reduce the thermostat a bit.
