Very cool set ups you have there. Thank you so much for sharing In your opinion what are the ideal temperatures for hatching/raising fairy shrimp? My room runs pretty cool in the winter so I'm wondering if I'll need a heater.

to be honest, im not sure. back in north carolina the temps would get over 100 degrees and the fairy shrimp survived in a tub in full sun.

my guess is that redtails like warmer water, somewhere around 75 degrees, but will tolerate very wide ranging temperatures. i know they can survive for a week without the temp ever dropping below 100 degrees...

at the same time, they live much longer in cooler waters. my suggestion, try to get them on green water if you can. if you cant, just find something that works and stick with it. i have never met any two people who raise these things the exact same way.

Cool thread. I used to catch fairy shrimp in a pond near the local junior high school when I was a kid. They'd show up in late winter. Would have them in coffee cans and jars in my bedroom.

Could be fun keeping them now...

a quick swipe of the live food culture. if you want to keep them as pets, something that works pretty well is raising them in a tank with green water and then moving them to a clear tank so that you can enjoy them. there are dero worms, black worms, redtail fairy shrimp, moinas, daphnia, and ostracods in this mixed culture.

I just wanted to add to this forum. I hatched red tail fairy very easily and love watching them. I had a ton of them and the water looked terrible so I changed the water and lost many of them. Tonight I was looking at the shrimp and noticed babies. Now I ciphered them out and don't think any were eggs, however even so I thought the eggs were to be dried out before they would hatch again. Well something is definitely happening with my lil tank of RTF shrimp. Oh and they absolutely LOVE the nasty water. Not sure when I will change it again.

Didn't think they did

I have no idea about their colonies. I thought they only hatched. As far as the "kind" I purchased red tailed fairy shrimp from a website. They do have the Thai Fairy Shrimp too. I just purchased them to hatch them and watch them. I like water fleas better. At any rate when I did a water change there were babies. I thought the eggs had to dry out and then re-hatch. Oh well just learning stuff, which is good for me.

Hey guys,

I've finally hatched my fairy shrimp. I set it up last night and they're already swimming around today! I just made some yeast 'soup'.

Here's a photo of my little hatching bowl that I got from the dollar store. (sorry you can't see the mini shrimps! they're too small now)

I've been checking out the thread since I just picked up some redtail eggs to help feed my finicky Scarlet Badis. I followed the instructions with a few eggs, then decided to throw a few eggs in a small bowl I had planted with Glosso, Hygro and Blyxa the day before.



I didn't hold out much hope for the bowl because I used Amazonia and it releases a lot of ammonia in the beginning, but WOW! They really took off. After 12 hours I could see about 6 wiggling dots. The next day (36 hours) there were about a dozen. The following morning there were almost 30 and this afternoon (4 days) it looks like there are around 60. They seem to be all different sized, perhaps from hatching in waves. I've been giving them a couple drops of yeast-water each day.

The bowl I followed the directions with only has a couple. In another day or two, I'll siphon some out of the planted bowl to feed to the Badis.

I just purchased some red tail fairy shrimp. And will be using a 1G mature planted bowl, that houses thai micro crabs and sakura red cherries. Is planted with Hair Grass, Java and willow Moss. Sits in the shade on the windowsill. would this be suffecient. Will feed with Spirulina powder

Don't red tail eggs have to be dried before they hatch again, or can they work from "wet" also? It would be really cool to have a total fairy cycle going.

reviving this thread... as you did!

to answer your question, yes, they typically need to be dried out.
that said, some of the eggs dont actually need to be completely dried. some of them will hatch out just by doing a water change. my guess is that a water change increases the osmotic pressure. after a while, the water gets saturated with dissolved solids, and doing a water changes tricks the eggs into hatching again, despite the fact that they never actually dried out to begin with.

its kinda like triops. most of the eggs need to be dried out, but a small percentage(maybe ten percent?) will hatch without actually being dried out, they just need fresh water, which might simulate a new rain.

by doing water changes after the fairy shrimp have been laying eggs for a couple weeks, i can keep a culture going for quite a while. and if it ever does completely crash, i just dry them out, rehydrate, and THOUSANDS hatch out.

I wonder if the ones that don't need dried out would be naturally bred for a strain of regular producers in a regularly maintained tank?

Just read this thread.. as I've ordered some Thai fairy shrimp.. and been looking at the Arizona site's red tails as well. Would the consensus be that the Red tails are the easiest ones to manage ?

I have various fish, including some dwarf chain loaches, that I'd much prefer to feed with live food. The response they show to, say, black worm or adult brine shrimp is much more enthusiastic than the one they show for dry foods.

I also keep Bettas in 2.5G tanks without filters or bubblers, instead, they have plenty of plants and a light. The fish are doing fine, testing always shows 0, 0 & <10. About half floaters, frogbit mainly, half a mix of fern, moss, anubias, H. difformis. Anyone think a tank like this would suit keeping the red tails or the Thais ? Temps might be a problem, it's hot here in summer, but they changed the heating system so it's fairly cool in winter now. The tanks in the one room, that I don't have heaters for yet,run around 70 - 74, and I'm debating whether I need to put heaters in or not. Before the change, it was always about 90F, and I ran fans all winter instead.. so still trying to figure out if the fish will be all right without additional heat or not. The shrimp sure don't mind the temps.

I am actually hoping the fairy shrimp eggs will also contain other critters. I'd love to get some more Ostracods, and would not mind other things such as cyclops or rotifers, etc, they all make great fish food. I had Ostracods for some time but they didn't breed well, and I might not have been keeping them in the right conditions.. they came from pretty stagnant pots of Lotus plants, and I had a sponge filter going in their tank, and only a few duckweeds for plants. They might have preferred still water, like the fairy shrimp seem to. Haven't been able to find a source for Ostracods on their own, unfortunately.

And I also have a bunch of moina eggs coming, which I hope to be able to keep going well enough to use as live food. I'm a big believer in living foods, and two of my four Bettas are seriously picky, often they refuse anything that's not alive. Frozen BBS are taken, sometimes they'll eat frozen bloodworm but mostly, they want it wiggling before they try it. Hence the fairy shrimp.

I'm not very keen on trying brine shrimps, don't really want to deal with the salt water at this point, though I may later. Currently also trying to get a colony of scuds established for feeding, the one Betta is a dead keen scud hunter, he actually killed off all the scuds in his tank, he's got a 5G to himself and some snails. He wiped out the scuds in a week or so of enthusiastic hunting. He seems to prefer bottom feeding, odd fishie that he is, often ignoring fruit flies or other insects I put on the surface that the others take pretty eagerly.

Anyway, just wondering if setting up another small tank like I have for the Bettas is likely to work with the red tail or Thai fairy shrimps.. Feeding them shouldn't be too hard, I've fed moinia before with yeast, and normally have cultured green water on hand too, which I feed to larvae and filter feeding shrimp and clams. If keeping them in green water works, that wouldn't be that hard to arrange.
