It’s time for the gentle march towards the cold season to begin and with it a busy time for the water gardener. Indoors, it’s always tropical.


  • Keep up control measures to contain and remove falling leaves to prevent algae issues next season.
  • Towards the end of the month, raise pumps from the bottom of the pond to restrict turnover and ensure some undisturbed water at the deepest point of the pool where fishes can rest
  • Consider a preventative treatment for parasites or any lesions whilst temperatures remain high enough for medications to be effective. Many fish losses in early spring are due to the rigours of winter
  • Feed with a low-temperature diet whenever fish seem interested. Take care with species such as orfe and sturgeons which remain active (and hungry) at lower temperatures


  • We often see rare and expensive fish but every species is special with its own tale to tell. Take a bit of time to find out about the ancestral home of your favourite fish and see if you can alter anything to make it feel more at home. Most fishes are captive bred and many don’t exist in the wild but we’ve all got wild ancestors somewhere
  • With dark evenings comes the opportunity to spend time reviewing your aquarium and problem solving. What would you change? Algae issues? Snail problems?
  • Fallen leaves can be a great item of decor for achieving that forest pool look. Collect and soak oak and beech leaves from clean sources or alternatively consider the dependable, packaged version in the form of Aqua catappa leaves. Many familiar fish thrive when given this little slice of habitat and some dwarf cichlids and catfish are real leaf-litter specialists
