For my photography project, I was able to do a photoseries on the development of Corydoras sipaliwini fry in the first 7 weeks of its life.
With a big thanks to Roland van Ouwerkerk for letting me raise some of his fry.

With the 3 remaining eggs, I found the 'shells' of about 10 others (there are some young assassin snails in the tank, that I haven't been able to catch yet and I think they might have eaten the other eggs).

But I could very well be she has some 'leftover eggs' or something.

Don't think the second one is ready, yet ;)

only one looked like she was ready. But who know's?


I really don't understand these guys anymore. Only one week later, the male is trapping a female again in the same cave (he abandoned the first eggs after 4 days. I found only 3 of them and put them ...

That´s a bit difficult…My first instinct would be; ´sure´, but photography is how I make my living. It’s getting increasingly difficult to get work and it’s getting very competitive. This project is a big deal for me. Some people even advised me not to share any of the pictures, until I was ready to ...

I only have experience with one Ancistrus species, L159. They were captive bred and spawned for the first time 7 months after I got them. I'm not sure how old my fish were when I bought them, but if I look at my own fry, I would say between 3 and 5 months old. That would mean they were between 10 ...

Yes ,I did and thank you for the compliment!!
I'm working on a photography project about the Development of different kind of animals (I posted one of the pictures here https://www.planetcatfish.com/forum/viewtopic.php?f=5&t=45695&p=309227#p309227) and created an under water set-up/studio for fish ...

I'll do my best, but it would be even better if they would let me know (if I have a second female) the same way this female did .

I can confirm now that I have at least one male and female, because they spawned last night .

I'm really surprised, because of their size (only about 6cm TL) and the fact that I bought them only 3 months ago. I will try to do another photo series on their development, so I'll keep you posted!

I just took another look at the pictures and I see now what you mean by nr. 2 and 3 having a higher bodyshape.

It's really fun to see new things eveytime I look at them

Your fish are L201, no doubt.


Well, that´s sort of my point, I know what I have right now and don´t want to ruin it :d My LFS´s supplier is really good at mislabeling fish, so I can´t really trust them. At this LFS L201 (could be wild caught, could be tank bred) is also 2x as expensive as what ...

Thank you very much, guys! This really helps.

The comment about contradens is a good point as well. I made a deal with my LFS to exchange my juvanile L159 for some new fish. The plan was to get 1 or 2 new L201, but it's not their speciality, so it's up to me to determine if their fish are L201 or ...

Thanks!! That´s better news than I expected :).

If I want to buy 1 or 2 new additions to the group, is there a characteristic (head shape, body shape etc.) I have to pay extra attention to, because it might be visible even in non-mature fish, or should I just pick the best looking fish and hope for ...

Thanks!

I don't want to be stubborn but in my opinion fish 1 is 100% surely a male. I can spot very long odontodes on the first ray of his pectoral fin with my bare eye's. It's probably a very chubby male :).

This is a close-up picture of this area of it's body.

I didn´t really measure them. Fish 2 is app. 6 cm TL. Fish 1 is bigger and the other two are about the same size.

Hi Everyone,

Yesterday I was able to take some pictures of my L201. One of them is cleary a male (visible odontodes on his fin), but I was wondering if you can help me with the other three. Or are they still too young to sex?

Fish 1 (male):

Thanks!

Yes, I did make the tank myself, but it´s a very simple one. I use a standard 30x20cm glass tank (in The Netherlands you can buy them in almost every pet shop for a few euro) with a white background.

Today, I had to move my Ancistrus claro group to another tank and took advantage of this oppurtunity to get my phototank out and take some pictures of this beautiful species.

It is 3 pairs of L134 and some cherry shrimps in there. Maybe I will occasionally add some different fry that I want to grow out there for myself. But that's it.

I did the exact same thing as you did before. half circle with 2cm 10ppi and 3cm 20ppi. Did not need no cleaning for 2 years on a ...

Thank you for sharing you experiences with the HMF. I was curious how many fish you are going to keep in the 100x40cm tank.

I'm using HMF's in my breeding tanks as well and I really like them. I've made a quarter circle filter with 2 sheets. A black 2cm one on the outside and a second (blue) 3cm ...

Thanks everyone!!

I did use a special photo tank. The first animal I photographed for my series was a black dog/puppy, so I decided to use a white (studio) background. The consequence was that I had to use the same background and lighting for the fish photo's as well, to make it a consistent series ...

A while ago I started a photography project about the development of animals in the first few weeks of their lives. At a certain point, I was getting really frustrated by being so dependent on other people, that I started looking for animals that I could breed myself. That's how I got my first ...

Really great to hear that your fish are recovering and doing well. Good job!!!

I had the same problem; how can I give them places to hide but still enough free bottom space.

This is what I have come up with so far:
https://farm5.staticflickr.com/4312/35887227051_d55711973d_b.jpg

I only use wood with a root structure, that needs minimal contact with the substrate, so it ...

I feed them twice a day. In the morning 5 days a week different kinds of frozen food and the other two days Viformo and in the evening mostly Bassleer. I'm not a big fan of tablets (if I feed them, I break them into little pieces first) because I think it's better for them if they have to work a ...

Yes, they can recover. Three months ago I bought 9 C. loxozonus, which all turned out to have badly damaged babels. This is what they looked like when I bought them:

And this is what they looked like after only two months or so ...

Ok, no C. surinamensis then. But what do you think, one species or different species?

Hi Eric,

Thanks! I guess without more info on the catch location, it will be very difficult to tell what they are. In the Cat-eLog there is a comment with the surinamensis "Mistakenly sold as Schwartzi", so it happened before.

My biggest concern is that if they accidently start breeding, there are ...

Hi everyone,

A while ago I bought a group of 8 Corydoras schwartzi. I started with 6 and got 2 more from a different store (same supplier) a few weeks later. One of them looks a bit different: he has a black stripe/spot at this dorsal fin.

Hi everybody,

Last week I was lucky to find the Corydoras polystictus at my LFS and I´m now the proud owner of nine of these little guys. I´ve been searching the internet to find some more information, but there´s not a lot of info available, so I hope any of you can tell me some more about this ...

Thank you for the very useful info. I already feared that animal protein (you're right, I feed mostly dead animals like artemia, mysis, black mosquito larvae, daphnia etc.) would be harmful to them.
In the other aquarium (were there is still a lot of free space) is a small group of Ancistrus claro ...
