Bunocephalus coracoideus spawning

Hi, got a chance to film my Bunocephalus coracoideus spawning.

It was 2 AM when I decided to check my tanks before going to bed. When I turn on the lights I saw some unusual behavior of my group of B coracoideus (2 females and 3 males). So I turned on the tank lights, and 5 minutes later the first spawning occurred. It was right in front of my eyes, it was so clear, the light was perfect, the cell phone in my hands, the fish framed on the camera, but I just took a photo instead of a video. I couldn't believe. Fortunately, it was not the only spawning.

This video shows the female just after the first spawning. It was like Eric's article (https://www.planetcatfish.com/shaneswor ... cle_id=532) describes: "she explosively released a plume of eggs, like a volcano erupting", but the eggs were all attached to her right side as we can see on video.

The second video shows the same female trying to spawn again but this time no eggs were released.

The third video shows the courtship and the moment they engage in the spawning position. No eggs released again. Same female

Fourth video shows the same female spawning, this time it is possible to see more eggs attached to her body.

All the time only one female was active, and all the three males. It's the same female in all the videos.

Congratulations! They are a sight to watch, aren't they?

Cheers, Eric

Thanks Eric. It was very unexpected. Actually I was concerned if they were ok. There is not a lot of places for them to hide. And I was not sure if they were eating enough, because there is a lot of corys in that tank.
But I feel very lucky that I was there at that exact moment.

The only thing that I think it was different from the article is the position assumed by male and female. I think the female was pushing the male upward.

Yes it does look like that in at least one of your videos. Interesting. Maybe it has to so with which parent is chasing? And if both can do the chasing, does it affect whether or not eggs are released? I ask because in my videos, females always initiated the interaction by judging males.

Cheers, Eric

Hi Erlend
Id say they look much more like Xyliphius - I am 99.9 sure that they are not Bunocephalus coracoideus. Whatever they are, great job with the breeding

Not sure what you're looking at, but these are definitely , not .

And how does Erlend figure into this thread?

Cheers, Eric
