they will breed again more than likely. Keep the eggs in there, you should see black dots on the eggs tomorrow night, or by the next morning for sure. If you don't they are not good. It takes them a couple times sometimes. There is a guy on this FH forum that had this same pair and he got some pretty neat fry. Not all where nice, but there where a few that had some great traits, and looked really cool. GL with your project!!
