Update 08-Dec-2012
Check of the tanks today and discovered a mini spawn in the main breeder. I didn't look thoroughly but managed to count (8) viable eggs and (1) non viable one. It was actually the non viable egg that caught my attention as it is a white ball sitting on the substrate.
This comes on the heels of a major rescape of that particular tank. Its part of my de-duckweed and de-snailification process. I completely removed every plant and ensured they were snail free, scraped the glass and removed the moss wall. I hadn't put the moss wall back in as yet and is on the schedule for today.
So today will be a water change, CO2 change and placing the Subwassertang wall back in preparation of the hatching.
