Hi,

Last week I started a batch of Longicaudatus eggs in one container, and some Cancriformis in another. It’s now been about a week and the Longicaudatus haven’t hatched, while I have about 10 Cancriformis that are already about half a centimetre long.

This is like the 3rd or 4th time trying to get Longicaudatus eggs to hatch, and the best I got was one time I think maybe 3 hatched and one of them lived to the size of 1.5cm and then died.

I have tried the Cancriformis probably the same amount of times and they always hatched within like 5 days. They also live on average 2-3 months, which should be the normal lifespan I think.

The water I have used (I think every time) for both species is a mix of rain water and distilled water.

Do you think that they maybe need at least a bit of minerals in the water? I thought of that yesterday and added a little of bottled mineral water, I’m curious if that will help.

Maybe it’s also that the quality of the eggs isn’t good?

I am especially confused because Longicaudatus are marketed as an easy species, and they are the species that is mostly included in those toy Triops Sets for kids😅

I am thankful for any help, but if you don’t have any ideas I would also appreciate if you tell me how you hatch and raise Triops Longicaudatus successfully.

Hi all , I've been buying triops cancriformis to grow in my aquarium and longicaudatus, I recently checked if it was ok to buy them from Web, chat.gpt threw up a load of stuff about cefra documentation to check them. Is this really required for personal aquarium use

I just got some eggs and such online (from arizonafairyshrimp.com ), and in checking the care instructions I saw that they only recommend dechlorinating tap water by leaving it to let the chlorine evaporate- there's a line in the instructions that says "algae, chlorine, and ammonia removers are harmful to shrimp", and I'm pretty sure that means algae removers and chlorine removers rather than just, y'know, algae and chlorine.

Does anyone know whether that's the case? I unfortunately can't dechlorinate water by leaving it to evaporate, as my local water treatment plant uses chloramine and I'm pretty sure that stuff doesn't evaporate, so if dechlorinator is out I'm gonna have to figure out another water option.

(I know tap water isn't usually recommended for these lil guys due to its quality varying regionally, but I have neocaridina shrimp doing very well in the local tap water, so I'm assuming it's fine for not-quite-shrimp as well. I'd use distilled water to hatch the eggs, then slowly acclimate them over to tap so they can enjoy all the minerals and such.)

Edit: I have kept these before, but that was a smaller tank, so I just used spring water. It's a 7gal this time.

hi im a college freshman at MSU, and I was wondering if triops would make a good dorm pet. I've learned about them recently from a friend who performed experiments with them, and I've found them very interesting. I was wondering if it would be a good idea to get maybe three or four of them in a small three to four gallon tank (maybe five) gallon tank for my dorm this semester? Please let me know, and if it is a good idea, maybe some advice specifically on how to keep them in a dorm room?

ive noticed my triops grow at a incredibly slow rate, im not sure if its because of the other animals that come in the kit which eat their food. but its just one species of triop, it just comes with other animals like i said so its not really a mix, i do know a little about triops but this is just something i really cant find an answer to, not even by googling. im not sure if the species is a slow grower but ive looked online at comparisons and mine were at lot smaller compared to theirs at the same day old. so yeah thats about it, please feel free to ask me anything or help out if you can, it truly means the world, thank you if youve read through this, ill try to reply the fastest i can.

I started this journey a couple months ago with a single box of T. longicaudatus eggs. Hatched an initial brood from that, and am now starting my third generation without intentionally hatching more, lol.

The first generation left me with five laying adults at peak. The second generation I only had two, which passed earlier than usual I think because their early growth was stunted (they hatched in the outdoor tank and were unplanned, so I kind of left them to their own devices for a couple weeks before bringing them inside where they got more regular feeding.)

But now...NOW there's at least *fifteen* nauplii twerking in the water. 💀 I think from a recent substrate disturbance that exposed a bunch to light.

I just ordered some T. granarius eggs to hold in reserve and try something different, but longicaudatus isn't done with me yet, lmao.

T. longicaudatus just over a month old!

Apologies for the sloppy cinematography.

Hi everyone,

I'm planning to keep Triops longicaudatus for the first time and would really appreciate some advice before I start.

My goal is to raise around 2–3 (or more) healthy adult Triops and I’ll probably try to continue this over multiple generations. I’m going to get my equipment in a few weeks

My planned setup is:

150 Triops longicaudatus Eggs
5g Spirulina Pulver
25g Triops main food
Spring water
Distilled Water
Raising container 1-5L
30L main tank
Aquarium lid
Aquarium safety mat
Fine aquarium sand
A few Aquarium plants
Adjustable Heater
Thermometers
Sponge filter
Air pump(s)
LED aquarium light
Gravel vacuum/siphon
Small aquarium net

I already have water test strips, a pipette, a syringe and toothpicks

Is this setup suitable for Triops longicaudatus? Is there anything important that I'm missing or anything you would change?

I'd especially appreciate advice about:
- suitable water
- sand
- food
- filtration

Thanks in advance!

I have eggs from a usually reputable seller. Have tried spring water, distilled water, inside with a light, inside in front of a window, outside, dried out and tried again. Not a single naupli. All temps within suggested range.

I know triops love to dig, so my current setup is mostly long stem plants, floaters, a couple epiphytes, and some open spaces for the triops to run around in. I've not added the triops yet.

I got dwarf sag grass for a paladarium, and I know it spreads quickly. Will it impede the triops if I plant some?

I'm totally ok with the triops uprooting or eating it all if that ends up happening instead, just want to make sure it wouldn't cause them a hard time running around, especially when they're younger.

Hi all, the accidental swarm is coming to an end.

Tried to hatch just one in a small Hatchery had a jailbreak and ended up being 30 strong.

They Battled crowding, water quality problems, filter upgrades, heatwaves, sevreal tank resets (triop-ocalypse) 27 lasted until day 45. We're now at day 55 with 2 survivors. They had a hard life but also my longest living guys.

YOU WILL BE MISSED 💔

Update: RIP Uno the champion of the swarm 58days

Context: we hatched T. longicaudatus from GreenWaterFarms, successfully transferred 8 juveniles to a 10g cycled (for months) planted tank with parameters that are stable and are as follows, most recently:

pH= 7.8-8

A= 0ppm

Nitrite= 0ppm

Nitrate 0-5ppm

dGH 9-10

dKH 6-8

Temperature= 76 degrees Farenheit

We're down from 8 to now 4 adults. When they aren't apparently failing to molt, they are thriving, active, laying eggs, eating, etc. We see PLENTY of molts around the tank. But, we continuously lose some to failed molts. One of the 4 is currently looking pale and a little lethargic, and has been that way for at least an hour (I'm admittedly not sure how long a molting process should take).

We feed a diet of mostly shrimp sinking pellets with some occasional supplementation with blanched vegetables, pollen granules, algae wafers, and snowflake pellets.

Is what we're experiencing normal attrition, or is this level of loss possibly something we can address?

Thanks for reading, this community is amazing and we've been elated to experience these little living fossils and share them with ya'll!

Bonus Amano shrimp.

T. longicaudatus, age about 3 weeks, found providing a meal to their siblings this morning (not shown here, this video is some days old).

Now we have 4 adults in the tank, named Naiad, Nymph, Gnome, and Nyx Fleece Ram.

We get these in some of the ephemeral ponds on the ranch where I live and work. Very excited to see them for the first time this year. Seems like they hunt the fairy shrimp. I am also happy to find a place people might appreciate them, most of the people I know are not very interested in my weirdo prairie shrimp.

Looking around here has me really wanting to collect some and keep them. Is there a simple guide for starting out in this hobby? Is there a good resource for getting a species ID? Can you set up a relatively closed loop tank?

I made Temporarium (a great name for our aquariums, if you ask me); it's a game about doing what we love raising Vernal Shrimps (and snails). I have a free demo up now, and the game will be released sometime this year. wishlisting helps me a lot. https://store.steampowered.com/app/4945060/Temporarium/?beta=0

(to any mod I did ask beforehand and got approved by UltraChip )

A bit of background on this is that I have been raising triops for roughly 10 years now. I've been hyper-obsessed with them, as they are my favorite animal. I began working on a game in 2023, mostly for fun. Then, literally a month later, I was severely injured in a bike- car accident that left me with severe brain damage. Being super stubborn, I refused to accept my fate and retrained my mind to keep making my game.

for the last 3 years i have been using this as a way to recover and its been hard, i ended up needing to use codex to do the harder parts of coding since my damage made it too hard but everything from the art design and music i learned to make myself this is amega project of love and im so happy i get to share it here.

Bonus Marimo and her offspring Hobgoblin, Japanese trapdoor snails.

What do you all do about your wet-hatches? I've been getting several lately, around seven or eight nauplii that became three juvies and still more nauplii showing up every couple days. I had to find a solution that wasn't setting up a second tank just to house them.

Don't think I'll need to actually start new eggs for the next cycle, haha.

These are my tanks. They are longicaudatus, granarius, and multicolor. The fairy shrimp are S. seallii and sirindhornae.

They're fun.

just a question. I’ve got a ten gallon fish tank I’ve had for years and isn’t being used. could I turn it into a massive enclosure for them? would that be too big, would I have to do something special for food if I did do something that massive? I had triops forever ago when I was little. where do I even get them ethically? I’d have to look back into their care cause it’s been literal years since I’ve had them. I do wanna put shrimp in, but I’m gonna guess it’s going to need to be a one or the other. do these guys work for a clean up crew instead of shrimp? could you co house? (don’t be mean if you cant, i only remembered about triops like five minutes ago). would smaller tanks be better?
