I'm not sure if there was a Hoplosternum bubble nest when the spawning happened.

Just wanted also to say I'd be DELIGHTED to add these pictures to the catelog. Is this something you'd consider?

Cheers,

I just sent you the pictures.

great shots of the baby! he is adorable!

Hi!!!

Nice and interesting!!
did you measure conductivity??
Your pictures are superbe and so is this little Platydoras!!
Cheers

Wow, I'm so glad this happened. I have started paying far more attention to my agamyxis breeding project since.
I noticed the regeneration period of doraidids in general is quite short in the wild. Does anyone think that doradids in the wild breed in their first year?

Happily you inquired after opinions, as I don't have anything else

I got 3 Platydoras armatulus (gotten as costatus) which I have for 20 years now. Breeding at the tender age of 1 is almost exclusively done by animals which do not reach a high age. Therefore, I would guess these Platydoras will need to be over 3, perhaps 4 years of age before they reach maturity.

I never kept Agamyxis, but the above might still be the case

Great news! I discovered another baby Raphael. This one is bigger (~2 cm).

Wow,

so small and already a chainsaw alike ;)

Regards.

Great news indeed.

Amazing, the way the spines are developing. Beautiful pics

Amazing. Please do keep us posted with new info/pictures!

stunning things going on in your tank! Nice fishkeeping skills!

This is the one I found later (about 3 cm now). The first and smaller one is still under 2 cm long.


The weekly water changes (50-60%) make the male very active. He dug a ~10x10cm pit to the sand in his cave immediately after the last water change. The male bited the fins of the female when it swam into the cave. This is probably a spawning ritual. However I didn't get eggs this time. The male has changed more orange.

This event is such an accomplishment and my congratulations on the achievement.

It amazes me that any fry have survived let alone the fact your fish bred.
I have a suggestion for enhancing the chances for more fry surviving.
I would provide a glass baking pan filled with hollow ceramic bio-media cylinders.
You could periodically remove the pan and check for small fry hiding or wedged inside the small caves.
I use this principal in permanent set ups for breeding dwarf Corydoras spp with good success.
A 9 X 16 X 2 inch glass pan would provide many very secure hiding places for the fry. They look like they have serious predation threats to overcome and some have but for every one you have found you may have lost 100.
I would routinely and alternately squirt some hydrated shell-less brine shrimp eggs or chilled newly hatched brine shrimp nauplii into the pan full of ceramic caves in addition to some fine ground sinking fish food mixed with water with a baster.

I concur with Bas that fish that live to be decades old probably need 3 to 5 years to reach sexual maturity.

It is very cool to see your photos of these small fry at different stages of development.

Wow!

I'm deeply impressed. This is truly good news!

Keep the pics coming

Here is a new video about my little jewels:

Great video - they've grown lots in 4 months!
Still amazed at the achievement, and good to see, lke their parents, they are active during daylight hours.

They are active only after water change.

Seen this?

Interesting. I believe that many so called hard to breed fish are being bred by accident by fishkeepers all over the place without realizing what a big deal it may be.
I think If PFK did a feature where "regular fishkeepers" i.e average joes that keep fish but have not much interest in their natural history, sent in info/pictures of chance breeding we would all have a bit of a surprise.

I think you may have something here.....
