I know that light has an effect on algae. Does heat? These past couple of weeks I've had some appearing,and wondered if it was down to temperature rise? Thanks.
No heater, it's my cold tank. 80 litres. 2 weather loaches and 5 danios. They are in a corner with no direct sunlight. They get 11 hours a day with the light on. Has been fine for 18 months, but not now. My 2 tropical tanks are fine. Just this one.
Sorry, but according to my book, and a PFK article, danios can be kept in temperate tanks. Also, both my local aquatic outlets sell them in both the cold water and tropical sections.
