For a while I was trying to determine the sex of the Banggai Cardinals that I got a couple months ago and it looks like last night I got my answer. I noticed he wasn’t going for the food when I fed the tank which was odd since my cardinals are normally super eager feeders. Then I saw how big his mouth was and I caught a glimpse of some eggs in his mouth, so congrats to the new dad!
