This weekend I'm planning to empty all my 200ltr drums and bathtub's in the garden!
I normally leave them sitting over winter and in spring they are full of nice Green Water. Once the temperatures are high enough I put a guppy trio in each of them. Mostly I use the drums for experimental crossings but also to create large numbers of offspring for fixed strains.
Harvest is always very exciting - you never know what you will find within the offspring. But also the pure strains are interesting because you get a huge number of fish you can select from and only use the very best ones for future breeding. Fish from outside are always a real booster for my strains...
Stay tuned - will post pictures from the harvest :)
