Bristlenoses do need a heater.

Thanks for your note about my Bristlenose plecos - I haven't got a heater in my tank but because of it's location it never goes below 22 degrees C and is usually a bit higher. Do you think I'll have problems with them over the winter when it might drop lower?

Also just to update everyone who has very kindly replied to my posting - yesterday evening I tested my water straight from the tap and it gave a Nitrate reading of somewhere between 25 and 50 and my tank was between 50 and 75. I've been looking for Hygrophila plants and am now stuck because there are several different varieties - should I be looking for a specific one? Again, thanks very much to you all.
