Woohoo! I just had another spawn of my caudos. So why does this excite me? A couple of reasons.
First, it has been a while since I’ve had a spawn. If you read the blog and can remember, I posted back in May of 2020 about a fish order I received from Dave Schumacher (Dave’s Rare Aquarium Fish). That order included five caudos. It didn’t take long to get my first spawn from them – six weeks in fact.
Back then, I made no attempt to remove the fry from that initial spawn and instead just let them grow out in the tank. The brood was not very large to begin with. I think I had about 20 survive to juvenile status. With such a small tank, the social construct became pretty gnarly once those juveniles got a decent size. But that took a while. Caudos don’t grow very fast. Needless to say, there was no additional spawning activity that I was aware of. Furthermore, I upset the tank dynamics when I removed most of the juveniles and split the remainder into two tanks. But I digress.
The second reason for my excitement is that this most recent spawn is from a different pair. It’s from one of the original males I received back in May 2020 and a female from that first spawn. I moved the dominant male, from that original shipment, which was also the parent male from the first spawn, to another tank. The dominant female from that first spawn got accidentally netted and sent to my LFS with most of her offspring.
Sadly, it took a long time to get this newest pairing. The photo above is an older photo before I removed most of the juveniles from that first spawning. However, it’s the same tank where this newest spawn took place. There are three or four different shell types in the tank. The pair chose a muffin snail shell. Note in the photo that I pointed out the spawning shell. Right now, the offspring are just tiny wrigglers. In fact, they’re so small that you can’t see them against the sand unless they move. I tried taking a photo of them, but I can’t zoom in close enough for them to show up. I’ll update this post if some of them make it. I’m not going to pull them until they’re at least 1″.
I have been expecting a spawn for a few weeks. I knew something was going in the tank by 1) the changes in the behavioral dynamics that I noticed in all of the caudos and 2) the sharing of the muffin snail shell by the dominant male and one of the females. If you recall, I posted on 12/29/21 that I suspected I was about to have another spawn.
