I got some Xtreme Krill flakes from ACO because fish are supposed to go crazy for them and they're supposed to make color really pop.

The killis just spit it out...

It may take a few times for them to get used to the taste. I’m sure they have a different smell and taste than what they’re used to! My killis did it with fluval bug bites flakes the first time but now they eat them

No real update on the sick killi today. Didn't give her a bath because I spent most of the day curled up in bed with my own sickness. Some kind of stomach bug.

Almost every time I look in there she's hiding under the heater.

Sorry to hear that! I hope you get feeling better.

She didn't make it. She was belly up this morning.

But the others seem healthy. They're like guppies in that any time I walk up they will beg for food:

Sorry to hear that what a bummer!! The others in that photo are looking great! Do you think you can get a closer up photo of a male and female?

I think they were sleeping (or whatever fish do) so they weren't moving nearly as much when I turned the light on so I was able to get done close ups.

Males:

Looks like it's time to clean the tank...

Thanks for sharing photos! I know how difficult it can be to get good pics of small fish. They look so good 😍

I've read that they are ready to breed on average after 12-14 weeks. I put a male in with the females and he would approach the females but they never went to the spawning area. Probably still a bit small.

This time they were fighting without any food involved. One of them had the other by the jaw.

They seem really frisky! Are the annuals a bit more aggressive?

Yeah. For all they know their puddle will dry up tomorrow so everything is a high stakes zero sum competition.

So is it not a good idea to keep males and females together at all times then with the annuals? Or only if they are all sexually mature?

My thought on separating them was to make sure the females had more access to food. It also helped keep track of how many of each there are.

My experience is limited but from what I've seen with my mature pair is that the female gets harassed quite a bit if it's just a 1:1 ratio. Some people keep them separated, move a male in with the females for a few days, and then take him out a few days to give them time to recover.

I was worried that the skewed sex ratio could make it hard on the few females that were left.

@Fish Folk had more experience with annuals

Thank you for explaining that it definitely makes sense! If you had them all in a tank together and had more males than females turn out then the females would have a rough time fighting off all the boys from mating and feeding like you said.

They got a big upgrade today. Long term they will probably be consolidated to one tank as they numbers go down but for now males and females get their own 10 gallon tank.

This is in my garage on a metal storage rack with some wood placed over it.

The light is probably temporary. That's what I normally use for growing seedlings indoors. That 5g just had Christmas moss trimmings in attempting to propagate.

With killifish being jumpers do you think the males will try to make the leap to the female tank? My killis haven’t jumped but they make me nervous during maintenance up at the surface curious what my hand is doing!

There is a background between them so they can't see each other but yes lids are coming in the near future. I think/hope that they are still too young to really jump. Their last setup didn't have a lid and I didn't see them make any attempts. Come to think of it though, I did have the water level much lower...

It may be a good idea to find a temporary lid for now

I’m not sure exactly how high they can jump so you might be okay!

Woof... Double whammy.

I went in this morning and half the females were belly up and the males were all at the bottom looking pretty pale.

I think the 100% water change and possibly the fact that I used prime shocked the females. I did a small water change with just tap water, added extra dechlorinator, and popped in an extra sponge filter. They seem to be pulling together now. None of them have died.

With the males it looks like the heater I put in there was dead and the tank was at 65 rather than 75... Don't trust cheap Amazon heater!

They all seem to be improving but none of them want to eat yet.

We'll see how they are doing in the morning

That’s never a fun thing to walk in and see! Hopefully they’ll all pull through! Even the females who were belly up are alive?! I’m so thankful I don’t have to worry about having a heater with my tanks being in the house! It’s a very easy thing to easily overlook you kind of just expect them to do their job and heat!
