Hey everyone!
My first spawn of this year hatched and so far they doing really well. So I decided to do a spawn log and hopefully everything will go well farther.
Last year I has lose every spawn I tryed to different reasons, first try this year was not successfull - had no eggs and female died shortly after.
So I have big hopes for this one, fingers crossed

They started to hatch yesterday evening, many tiny frys. More then I expected cause Betta Daddy was a bit overwhelmed with the amound of eggs so many stayed on the ground. But it seems like the hatched also and a big amount of them found there way back into the bubblenest or hanging around near by.

Parents are both giants, female is an yellow koi with in my opinion great fins, maybe a bit small for a giant. Male is multicolor/nemo based koi and a really big boy 😄
Originally I wanted to pair him with an nemo giant female, but as mentioned before this female died.
But I think the yellow one is also a good choice. I‘m hoping for many big colorful bettas 😄

Little Update on the fry.
They doing well, had some losses, but nothing dramatic. Like a few frys every day but it was a reeeeally big spawn like somewhere over 200 eggs so there more than enough fry left. Most of them are yellowish light based and some darker grey ones - so there might be a variety of colors. Some size diffrences beginns to appear, but i dont think this is giant related but normal in every spawn.

Size differences become more manifestly, there are some really big and some tiny fry. But the most fry are between. Spotted some which started to show iridescent scales - which is common for koi to start with.
I can’t tell how much are left, could be anything between 50 and 100. It’s hard to tell cause they like to hide in the moss and anyway the dark ones are harder to see.

Update on the fry:
They are five weeks old today and doing well, around 25-30 are left.
Two are very tiny, I think sooner or later they end up as food for the bigger ones.
Feeding them BBS now for about two weeks, waterchanges every two days and rised the temperatur a bit to push their growing. Started also to introduce some dry food, but they still like the live one more.
I‘m nervous about them getting their ventrals and a little worried that they are feed too long with microworms.
Somebody knows at which size or age they showing their ventrals?

Not sure when ventral fin appearance is regular but only one of my fry has visible ventrals so far - the biggest from the original spawn, the smaller two don't appear to have ventrals yet. They are 4 1/2 weeks old. I bet it has more to do with how fast/big they grow instead of how old they are. For reference, mine have been eating BBS since birth aside from some fry food in powder form.
Your spawn look amazing! So glad to see an update! :giggle:

Sadly there are really some fry without, with only one or really small ventrals.
For future breeder this is not so dramatic but it is still annoying. So next time bbs from the start or vinegar eels. The smaller ones have all their ventrals.
Colorewise the most of them look already pretty cool. Looks like most have red, so maybe no yellow koi - but that‘s fine, cause i have another breeding pair in this colore. Super excited about them to start marbling.

About a week ago I jarred the first males and already sold some females which definitly don‘t fit in my future breeding plans.

Some yellow koi males, waiting to see which one develops better colore

For now I jarred ten males, sold three females and have remaining six females and six males in the grow out tank - but I think I have to jar the remaining males in the next weeks.

And here a photo of my biggest male, who is interestingly one of the calmest males. And he changed colore and is still there, started purple-blue-red and now is a pearly colore with a bit red.
