Copella callolepis (sensu Zarske)

Hi all,
I've obtained five <"Copella callolepis"> .

I bought them as "Splash Tetra", although the vendor knew that they were another species of Copella, just not which one. We both thought they might be C. callolepis, and a look at TomC's web-site proved that is what they are.

I've only had them for a couple of weeks, but they've settled in very well and coloured up. I'm hoping they are going to spawn. I'll get a picture of them and keep you informed on how they are getting on.

I assume they are a black-water fish, mainly because they have tried eating pretty much everything including dried food, and even having a go at the Asellus, which are almost as big as them.

cheers Darrel

Hi all,
They must read the forum, when I got home they had already started spawning. Three of the fish were involved, and they showed a different colour pattern, with no lateral band, just a pale cream back-ground with very prominent contrasting dark dots. The male swam round rapidly and frequently entered a saucer shaped dead Beech (Fagus sylvatica) leaf, that was caught in the floating plants at the surface, and had less than 1cm of water on top of it. Eventually both the other fish joined him (the tank lights were on and I could see there shadows from underneath), at one point all three were side by side on the leaf.

The two fish, that weren't involved, carried on foraging and retained a darker colour with lateral band.

This morning there were quite a lot of clear eggs (probably about 50) adhering to the leaf, and a couple of white ones (presumably unfertilised) loose in the water on the leaf. All the fish seemed to be behaving normally so I've left the eggs on their leaf in the tank and I'll try and get some photos this evening.

cheers Darrel

Hi all,
A video of a pair spawning last night, apologies for the quality.


There were a range of leaves available, but they used the same one as the previous evening.

congrats darrel!

mine used the same leaf everytime aswell. that was also approximately 1cm. below water surface. though i wasn't as lucky as you. i didn't see any eggs.. -or maybe i just didn't know what to look for.
is it possible to grab a picture of the eggs? -is it a small clutch of eggs or are they scattered all over the leaf?
i hope to get some more of either callolepis or nattereri (i probably prefer nattereri), since i af a few lasting ones from earlier.

looking forward to see next update.

The leaf had sunk deeper into the tank and all the eggs were gone when I came home.

The eggs were all over the leaf (it is quite a small leaf), and they were smaller than those of C. arnoldi, but these are smaller fish.

They were transparent and you couldn't see them unless you lifted the leaf out. If there hadn't been a couple of white (presumably infertile) ones on the leaf, I probably would have assumed that there weren't any eggs.

Hi!!

As i was writing another post here, i spotted my only two remaining callolepis, spawn on a leaf near the surface. Ofcause i checked for eggs as soon as they where done, but sadly i couldn’t see any.
But i’m glad to see they are in the mood again, because they have been laying low for a while.

I had this species back about 1983-84, and have been trying to find them again ever since. At the time they were (mis)identified as Copella nattereri. I only managed to get one pair, but they did spawn in a very similar manner to that described above. My pair, however, had a floating leaf of Echinodorus cordifolius that they used. There was a shallow puddle of water on top of the leaf, which had one edge submerged. They slid up onto the leaf side by side, somehow staying under the water tension. I took photos, but when the slides finally came back, they were very bad. I did siphon some eggs off the leaf and attempted hatching in isolation. The fry were the smallest things I'd ever seen. At the time I was still relatively inexperienced, and was unable to find a food for them.

Just to verify, this is a photo of the male:

Hi chromedome!

Now, i don’t know where in the world you are, but i you are able to order fish from ruinemanns in netherland, you can get hold of some copella callolepis. I recently saw them on their site.
I got my callolepis by a mistake, because they where labelled as natterneri. Beautiful fish non the less.
Now i got one natterneri and two callolepis.

The nomenclature for these Copella spp. is fairly confused. There is a recent paper that tries to sort it all out, but some of the issues are really deep-seated because the holotype specimen etc. is missing.

Paper is Marinho & Menezes(2017) "Taxonomic review of Copella (Characiformes: Lebiasinidae) with an identification key for the species" and that calls this fish Copella nattereri "sensu Marinho" , which was why I put C. callolepis "sensu Zarske" in the original title.

I got the <"information and scientific references"> from @Tom C.

Thanks darrel!

That’ll be my goodnight read.
This evening my callolepis pair is at it again.
I came home from “den blå planet” (Danmarks national aquarium) an hour or so ago, and saw them. They have been swimming up and Down from the same leaf since.
Could those little white dots here be eggs?
On the other picture you can see them as silhouettes on the leaf in the middle.
