What kind of shrimp and killies do you keep?

Some shrimp will eat eggs, some will not.

Hi Mosiah ,

I have cherry and crystal black shrimps and my killies are ANN . I got 2 bunch of eggs hanging on the java ferns and luckily i isolated one bunch . The other bunch is already gone ^_^"

Do you know how long will they hatch? I put them in the same tank with a mesh to protect them from the "killer shrimps"

Thanks

Gabrie,

I keep many killi species, but no P. annulatus as of yet. I think two weeks or so they should start hatching, as they don't require being dried. Cooler temperatures means longer time required to hatch.

Cherry shrimp are very much scavengers, and love to eat anything they get their claws on. So would not doubt them to be the culprit in the caviar feast.

The only critters I have kept with my killies are otocinclus sp. and horned nerite snails. As these guys are only vegetarians, if they did eat any eggs I have not noticed.

Regards,

Thanks Mosiah ,

I will keep a watchfull eyes on the eggs Will plan to get another tank for the little ones


Thanks

Gabrie, all shrimps are opportunistic feeders and to these critters, eggs are just food. Once your ANNs are settled down, fed well and can breed, they will spawn again.

I cannot imagine what you mean by isolating the eggs but these will hatch between a week or two in our weather. However, you will have problems finding them because they are super itsy teeny weeny, semi-transulent and slimmer than the finest sewing pins.

It is not impossible to find them, much easier when it's dark. Use a torch light and shine on the surface. ANNs have a reflective spot on their head and while it's tempting to raise them separately, do so only if you are well prepared or you will surely kill them (I've done my fair share of that as well)

ANN fry feed on infusoria and other microscopic organisms for much longer than other killies before they're ready for daphnia or newly hatched brine shrimps. To prevent water fouling due to uneaten BBS, add ramhorn snails as clean up crew. Their poop will also help sustain the microscopic population.

Provide plenty of floating plants for refuge because as they grow, beware of sibling predation since the tinier fry will be food to the older ones. Sorting them according to size, into separate grow-out containers/tubs/tanks, is one way to minimize predation. I've done quite a bit of work on ANNs, so search the Killifish forum's archive and ask when in doubt. Read this as well. Good luck and enjoy the experience.

Forgot to mention this but Gabrie, if you find ANNs that look like what I used to breed, let me know. ANNs are very infectious and never fail to give me a very bad itch....

Hi Ron ,

I have the taken a few photos of the fish and my community tank too
can you help me to identify if the eggs are ANNs? As i got a few species inside

Thanks for your help and i have read your posts many times and when i saw the ANN at AMK i bought it Its real fun having these ANNS

Thanks

Gabrie,

Very nice pics! If you want to do some real breeding a species only tank is best. Ron has very good advice as usual, and I can see from his other post he is a big ANN enthusiast too.
Oh, the eggs next to the cherry shrimp don't look like any killi eggs I have seen, maybe Ron can shed some light?

Best luck with your killies. Careful, you might get killi fever like some of us, and decide to get more

Gabrie,
I don't want to shower on your parade but using that shrimp for comparison, those large eggs are unlikely to be from the ANNs. I figure it's either those long-beak fishes (can't remember what genus it was) or those Threadfin Rainbow (Iriatherina werneri), if there were females. Again, given that there were fry, I honestly doubt any will survive since there're too many predators and no refuge (the water surface is as barren as the Sahara).

Mosiah,
ANN eggs are tiny, translucent eggs, very difficult to spot and does not handle well (for repacking, etc). Stable, healthy young adults can be safely shipped in breather bags and in one trial shipment to the UK, all pairs survived the long-haul journey. BTW, I'm not an enthusiast but ANNthusiast !!

Hi Mosiah and Ron ,

Thanks for shading the light of the eggs ^_^" will try to make a killie tank after chinese new Year . And try to make a foot ball team of ANNs .

Happy Chinese New Year to all ,

I keep Iriatherina werneri, and those are not werneri eggs either. The killi eggs and werneri eggs will be clear, and scattered throughout the plants. Neither of these fish lay eggs in clumps. Also their eggs are way smaller than that. What other types of fish/snails/shrimp are in the tank?

[gabrie]

Hi Rother ,

I got another fish which is long beak... its shown in the pics with the killies. And they sure can lay eggs ^_^"

Thanks a lot

Gabrie

[stormhawk]

gabrie, the Halfbeaks are livebearers, which means they did not lay those eggs you photographed. I think those eggs are from the threadfin rainbowfish - Iriatherina werneri, the fishes in your last photograph, but Rother doubts it.

With Ron, I'd agree those eggs are not from the Clown Killies. They lay eggs singly on the leaves and roots of floating plants or plants close to the water surface. I don't think they lay eggs in clumps like what you were showing in the 4th pic.

Do you happen to keep any Ricefish/Medaka? Oryzias species. They lay eggs in clumps but carry them around near the belly region.

[RonWill]

HAH!! About time you came in JianYang. Thought you've dried those fingers of yours and no longer keeping fishes. I was thinking of Oryzias's egg but heh, my memory isn't any better these days.

BTW, Gabrie, that clump of eggs do look somewhat opaque and possibly not viable but we'll wait for your updates.

Rother, are you still breeding the I. werneri? The fry from these buggers, together with some Pseudomugil species, are a pain to raise if the right foods are not available when needed the most.

[Rother97]

Yes, as I write this I have a tank behind my desk with I. werneri, royal farlowella and German Rams. The werneri are so hard to feed that they end up being easy to feed, as in they're on there own. I have wads of java moss and some duckweed floating at the surface. The tank is well established and there are enough infusoria growing by now that it may as well be a pond. I have a divider in the tank to keep the two pairs of Rams from getting after each other and it has really gotten the werneri population increasing. They can swim through the holes in the divider to escape predation. So there seem to be 10 new fry every day now. Some are about a month old now and eating decaps as well. A few are large enough to leave with the adults now. I think.

I keep a 20 litre Sterilte tub on my desk that I move the werneri fry into as I scoop them from the surface. I just put some of the plants in there and give them APR a few times a day while I work at the computer. I dip a wooden kabob stick in the powder then touch the surface of the water. It disperses but does not sink immediately. They seem to stay full that way. I put some ram fry in with them to eat any food that sinks. The newly free swimming werneri fry are among the smallest I've had. Colisa lalia are really small as well.

Heya Gabrie !

Just about everything has been said already from our dear gurus, I'd like chip in and leave a little comment as an amateur if you don't mind.

I also keep ANN and I get eggs from them from time to time. Actually, they keep spawning in their big planted tank all the time but as you can imagine, it's a little difficult to find/get eggs from there.
Besides, ANN eggs are very delicate, you can easily damage them if you try to pick them. So when I want to get eggs, I just seperate 1 M and 2 F, give them a seperate small container with mops + some plants.

The eggs are really quite tiny, it's about the size of a female ANN's eye
They tend to deposit them in shady areas of the tank, in java moss or under big leaves if you want to look for them.
Good luck ! I really love ANN.

[zoothefreak]

hey i know this is a little late but those eggs are abandoned eggs from your Cherries... I had those too a while ago when my Cherries were stressed out the berried female dumped her eggs...

Killis like to eat shrimps but shrimps like eggs too
