I've checked for life in the bubble nest and did not find any. No tails were hanging off the the nest, no movement whatsoever. Did a 50% water change and added a filter to reset the tank. Will condition the male and female for at least a week before trying again.
I would like to thank the many emails I've received, thank you for your support and kind words. I was lucky for my F1 spawn, everything went smoothly. Suffered my first unsuccessful spawning attempt, hopefully the pair will spawn successfully the next time.
