Even if we want to do an experiment, must be able to find nice gf to keep. If not, it is not shiok keeping. Furthermore, to reduce any inconsistency, we must pick fishes from the same batch.
And we each need to have a few pieces in case of casualty.

Sgow grade small ranchus from the same batch is not the problem. How many you need? You try GW and I try CW and compare after 3 months.
