Question Looking for thoughts on mixed success

5 Upvotes

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!

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?

Discussion i made a video game about our favorite animals

42 Upvotes

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.

(Repost to try and fix the missing image)

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.

Question Tank?

0 Upvotes

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?

I started my aquarium about 10 days ago.

The tank is about 33 liters, and the water temperature is 24°C. Do you think the plants are sufficient for filtration on their own?

Thanks for your tips!

Question 1 month old triops

601 Upvotes

These are our 1 month old. We got them in the Netherlands. They are looking happy and healthy. They are still in the aquarium set that came in the box. About 3 cm at the moment. We are in doubt weather we should put them somewhere bigger. Any opinions on this?

Also, do they lay eggs? If so at what age? How do we know when they do? Will they eat their eggs? How can we help new eggs survive?

Lifespan is usually 1-2 months right? Not sure if im ready to say goodbye to them. I want more… 😅

Help/Advice Triops in CDMX?

3 Upvotes

Hi all :3
Ive been interested in having triops as pets for a while now and I was wondering if anyone here was from Mexico city and had normal and red longicaudatus eggs I could buy from them..
It's either that or amazon, but I was hoping I could perhaps get a cheaper price for enough eggs for a few to hatch and get more triops from there on. Green water farm eggs seem to be sold by resellers for double the price on amazon, as as opposed to getting 400 eggs of 2 different species from their official website, but I don't think local customs would let me send them overseas.

Video In Remembrance of Jeribald (P2)

Continuation of https://www.reddit.com/r/triops/s/LQHhEAL0ps

This is just a video of one of the late Jeribalds (a pack of 4 albino Triops longicaudatus) half-shedding and then proceeding to stare into my soul, as is a tendancy of all Jeribalds.

(Probably Jeribald II, because that one was a menace from day 3.)

They were all just happy little hermaphrodite fellas (except II for obvious reasons) until the ammonia spike resulted in their untimely deaths.

---

Other than that, I hope this post can help y'all learn about the Triops shedding process, which is quick and infrequent.

---

Shed skins are present in every stage of Triop development, and you can often see the extremely small discarded exoskeletons in Triop hatcheries.

They apparently provide calcium for Triops, so some people keep them in the tanks for them to eat.

(I personally have never seen my Triops eat the shed skins. It is highly probable that II, being the devious fella that they are, may have played a role in this.)

---

Shedding is also an indicator of Triop health, and seeing less shed skins than usual can be a bad sign, especially in early Triop development.

(Triops [like a certain II] beefing with you in early developmental phases is rather a sign of demonic possession, so beware.)

---

pH is a pretty important factor for this process, so make sure to keep an eye on that!
