Elevated Temperatures

[Martin Thoene]

Daytime temperatures here have gotten fairly high recently. No air in my apartment and soon the idiots redoing our balconies are supposed to be painting mine. But I don't know when. That means I remove my table and chairs every morning and shut the door before leaving for work.

So it's pretty warm indoors when I get back in the late afternoon.
Today, my Sewellia tank is a cookin' 82.7 F. All the fish seem quite contented and are pretty lively as usual.

My main River-Tank in the lounge sits under a ceiling fan and is a cool (not) 79.2F. The tank is also overdue for a water-change and evapouration has dropped the level around 2-3"! It evapourates alarmingly with the fan going.
All the fish are behaving normally apart from the Pseudogastromyzon cheni.

One pair have decided each other are hot and are spawning!

So much for keeping Hillstreams cooler all the time. No problem if you have LOTS of water movement like I do in these two tanks. Must do some water-changes though......

Hi Martin,

It seems we are seeing the same behaviour with the Cheni in our tank. The past couple of weeks saw the water temperature shooting up to 28-29 centigrade and now we keep seeing small fry in the tank. We are catching those we can and placing them in the breeding net.

As an update on our last batch of fry, the two larger fry have been released from the breeding net into the tank and have settled in well alas i believe we lost all of the small fry that provided the development photos :( . Of that group only one reached a large enough size to be released from breeding net and while it seemed happy in the tank for a couple of weeks it then vanished and has not been seen since. On a more positive note we have another 5 (or maybe 7!) baby loaches in the breeding net which are about 1.5cm long and are looking very happy, I think we will keep them safe in there for another couple of weeks :-) . In addition the past couple of days have seen another three little wigglers caught and added to the breeding net, they are about 5-7mm long.

We have started to use a house fan to blow air across the surface of the water and have been able to control the temperature that way, this has dropped the water temperature to a more comfortable 22-24 centigrade but is requiring water changes every 2 days to keep up with the evaporation.

How hot is the action getting your sewellia tank? ;-)
