Thank you Fish Folk. Yes, it's a nice tank. It runs between 20 and 40 Nitrates, I never fertilize and the Val grows like crazy. I've actually placed 2nd in an online aquascaping contest using this tank.
Anyway, as you can probably tell, the large fish in the photo has the female breeding tube. She is the one laying the eggs. The eggs are very organized and turn white and fuzzy in 2-3 days. She does guard them well and she doesn't eat them right away, but they are all gone within a week. I can't imagine the smaller dark one being 'talked into' fertilizing the eggs if it is a male. When she's laying eggs the other one stays away. They do display some odd 'breeding' behavior before the large one lays the eggs. The smaller dark one will shake and shutter as the larger female approaches it. As I've researched, that is typical breeding behavior.
Again, I appreciate your help. My plan long term is to upgrade this tank into a 75 gallon within the next 7 months or so.
