Okay I feel like I have been spamming my own thread, but some of these were too nice not to share.
First up, are two of the smaller males flaring at each other.
Then just a couple of the smaller males swimming around. You can see that in a group the males don't really develop the flowing white extensions on the caudal fins that they do when you just keep them as part of a breeding pair/trio.
After those photos, I got the mirror out and my biggest male and his father were having a great time flaring at their reflections.
This is the biggest male. He was moving so fast up and down the glass I couldn't manage to get him into focus.
Then his father joins in (these two are very similar in size now)
The two of them together (father is in background flaring)
Finally, my biggest male upset that I took his entertainment away.
I seriously love these fish. I have been browsing killifish forums all day. I can't wait to get some more.
