I really don't know if they are males. As for spawning, I have never had Naiad like this before. In the past when they spawn I see little depressions along the bank. Not seeing that this season. So, will this decimate the BG population or will I likely loose some more then level out?
I have used Aquathol and Hydrothol in the past and not had this problem. Sounds like the Aquathol may be a safer bet in the future.
