It has been many weeks since my last post when i was in the process of building my outdoor ranchu ponds. They are now pretty much complete. As you may expect there have been a number of modifications and improvements already made to them and I still a few more planned. On the whole though, they are performing tremendously and my small group of ranchu are looking well.
Temperatures have been far easier to control, particularly during brighter days when the ponds haven't warmed up like they did in the conservatory. The lids also appear to be doing a reasonable job preventing heat loss with a single 200 watt heater currently all that is required during the night intermittently to keep temperatures stable, even with evening temperatures below 10 degrees C at times, which is promising for the approaching winter. The ranchu have been kept between 15 and 20 degrees C, are feeding well, active, deeper in colour and looking healthy.
With the winter fast approaching it will very soon be time to start the gradual cool down. I hope to make it a very gradual process this year, and expect to have lowering temperatures well on their way by November. With the extra ponds now available i also intend to separate the sexes over the winter this year.
