Cory Losses

[Harlequins]

Done my weekly w/c and found 2 of my metae' cories had passed away... well gutted :{

I think its more than likely down to the scorching weather we've been having, the tank has been hitting 29/30 degrees all week,even putting bottled iced water in didn't bring it down much...

Its just gone back down to 24 degrees last night with the cooler weather and rain..

Hi Harlequins,

I'm sorry to hear about your loss. Hot weather, and the stress that results, can be very hard on corys. One thing to be careful about is the decrease of oxygen content in the water as the temperature rises. An airstone will help this situation.

Let me comment on something else I've noticed happening in my tanks in the past. I've seen tanks with several kinds of corys have one species die off, often by one fish at a time. While this is going on, other species in the tank will be just fine. I never did figure out why this happened.

I hope your fish are alright through the remainder of the summer.
