Doing the weekly water change when I decided to break open a clutch of eggs from my apple snails.. I was worried that they had been there too long and died. But they are all crawling every where :) do happy. Whilst wasthing the baby snails I noticed two of the smaller corydoras chasing one of the bigger ones. Looked like they were trying to get into a t position. I then went and checked the other tank and found two of the guppys are about to drop.
