Sunbird73 Posted August 22, 2010 Report Share Posted August 22, 2010 Well, just randomly decided to test some water chemistry to fill some time in, and noticed the water in my 54L tank was vy cold. Checked the plugs and sure enough it had been switched off somehow So, have switched it back on again - temp says 18 degrees (it was 23.5 yesterday morning) Have some panda cories & guppies in the tank. Do I just let it warm up slowly just with the heater? Or shall I change a bucket of water with 22 degree water now? Don't like them being cold but don't want to shock them too much by warming up too quickly. Guppies swimming around as usual and ate their dinner, but pandas are hiding at the back, and hard to see them. What to do?? Am worried about the panda's especially, they are favourites here! (tho I read they prefer colder water so might be able to handle it?? cross fingers - tho 18 degrees might be pushing it ) Quote Link to comment Share on other sites More sharing options...
Mr T Posted August 22, 2010 Report Share Posted August 22, 2010 Had the same happen in 200 litre tank. Was advised just to let it heat up. Quote Link to comment Share on other sites More sharing options...
Sunbird73 Posted August 22, 2010 Author Report Share Posted August 22, 2010 ok, will do nothing and twiddle my fingers nervously while it heats up. Tho I did find this: Corydoras panda inhabits clear river waters that are relatively fast-flowing, well-oxygenated, and flowing over substrates that may comprise soft sand or fine gravel. These rivers are usually well vegetated with assorted species of aquatic plants. The proximity of the home rivers of the fish to the Andes mountain range, and the replenishment of those rivers with meltwaters from Andean snows at higher altitudes, has led the fish to be adaptable to cooler temperatures than the norm for 'tropical' fishes - the temperature range of the fish is 16°C to 28°C, though the fish exhibits a marked preference for the cooler regions of this temperature spectrum, particularly in captivity. Indeed, the fish can, for limited periods, survive temperatures as low as 12°C, though captive rearing at such low temperatures is ill-advised. The native waters of Corydoras panda are consequently mineral-deficient, with a neutral to slightly acid pH, and replication of such conditions in captivity are recommended for successful maintenance. which made me feel a bit better!! Love my pandys Quote Link to comment Share on other sites More sharing options...
malevolentsparkle Posted August 22, 2010 Report Share Posted August 22, 2010 happened to me when I had cardinal tetras and a geophagus. no harm done and cardinals are meant to be very sesitive! Quote Link to comment Share on other sites More sharing options...
Ira Posted August 22, 2010 Report Share Posted August 22, 2010 Just let it warm back up. I wouldn't worry too much about it. I left one of my tanks unplugged for about 3 weeks, noticed the fish were moving a bit sluggishly and checked the temp, it was at 16°. They were all fine. Another one was outside in a sleepout in 0° for at least a week full of fry with no heater, no idea what the temperature got down to but it painfully cold. No noticable losses.

phoenix44 Posted August 22, 2010 Report Share Posted August 22, 2010 Yeah, you're lucky you had cories and guppies, both which are relatively ok in cooler waters! Quote Link to comment Share on other sites More sharing options...
Sunbird73 Posted August 22, 2010 Author Report Share Posted August 22, 2010 Tank is up to 22 degrees now fish are happy and fwimming awound (according to my 3yo fish checker) *phew* Quote Link to comment Share on other sites More sharing options...
Caryl Posted August 23, 2010 Report Share Posted August 23, 2010 Are you sure that is *phew* then, or *few* ? :lol: Keep an eye out for an outbweak of whitespot over the next few days. With a bit of luck that won't happen, as you caught it quickly, but be extra vigilant Quote Link to comment Share on other sites More sharing options...
