Unable to access triops-aquaristik.de from the USA

Apologies if this isn't allowed, I'm unsure where else to ask. I'm looking for the Mongolian fairy shrimp and can only find them on that site, but can't seem to connect no matter what device I'm on. Does anyone know the email for them or if they stopped shipping to the USA? I swear I ordered from them before

How many times do you lay eggs?

My Triops longicaudatus has laid eggs four times. Is this normal?

Today she said farewell to her hatchery and is braving the deep waters for the first time. I hope she survives this transition, it’s a big moment for her.

First time hatching!

After a failed first run, my triop eggs hatched last week! Two have survived into adulthood and I’m pretty sure they are a male and female (one is smaller and pinker while this one is larger and darker). I have named them Flotsam and Jetsam.

This is Flotsam’s second time eating a bloodworm. The first time, she came up and took them right off the tongs! Today was the first time they were big enough to eat something besides algae.

Can different species of triops live together in one fish tank?

I live in South Korea, and I want to keep black longicaudatus triops and red longicaudatus triops together. (I used a translator, sorry.)

Egg hatch ratio

So I left the eggs in there for two or three days, and they hatched and I count about a dozen little creatures scurrying around. It’s now been 5 or 6 days.But it seems like upon closer look most of them are fairy shrimp and there’s only two or three triops. Is that normal? Should I contact the company i got the kit from?

I finally got clam shrimp and Daphnia…

I was able to get in contact with Green Water Farms and they allowed me to buy some Clam shrimp from them, quite expensive but worth it cause the hatch rate is absolutely awesome.

Single Triops adult with a pea puffer-Hard no?

Ok before you freak out - I am pretty sure a “no” but I promised my daughter I would ask because she is begging for her birthday a pea puffer for our tank which is housing a sole 3week old triops (longicaudatus) named Big Red.

Housed in a ~7gal (once all the stuff is in)planted tank with sand bottom.

I am guessing we need to wait until Big Red has gone to the big light in the sky (Triops heaven?) but let me know if we can avoid my daughter getting morbid and counting down for my triops to bite the bullet.

Aquarium decorations?

Does anyone put (obviously) tiny aquarium decorations in the tank with their triops? Maybe like a tiny little cave formation for fuly grown triops to live in? Or is it preferred that they just use the sand to bury in?

Best detritus

What is the best detritus to feed newly born naupli with without causing a cloudy layer to form on top? This has killed my triops in the past

Unable to hatch triops

Hi folks. I’m having a heck of a time trying to hatch triops eggs. I’ve tried in a 3 gallon aquarium and in a separate small dish and can’t seem to get them to hatch. This is my second batch of eggs from greenwater farms. No idea what I am doing wrong. Have tried pure RO water, have tried cycled aquarium water, fresh tap water with conditioner, and combinations thereof.

Any help would be appreciated.

Species ID?

Trying to identify this species, my guess is T. longicaudatus Gonochoric or T. Granarius.

Where do I buy Clam shrimp for my Triop tank?

Sorry I’m bringing up Clam shrimp in a Triops Reddit but I am really fascinated by them. I know TriopsKing sells them but as of right now they still haven’t sent my package, and the ones on eBay have bad hatch rate sadly. I can’t buy from Arizona Fairy shrimp either due to them closing out Canada. Any help is greatly appreciated!

Found out something you might find interesting..

So I remember reading a post on this sub “Permanent Triops” and wanted to test it out. I basically noticed that babies were starting to hatch in my aquarium and started adding spirulina powder to the tank. It is quite rare but I actually have a juvenile now in the tank. So if you notice little naupli twitching in the tank, wait a day, and try adding some spirulina in the tank like I did. You might just get lucky.. 😁

Is black polymer coated silica sand toxic to triops?

Does anyone have any experience using Stoney River black polymer coated silica sand?. Is it toxic to triops at all?.

I added it to my tanks a little over a week ago, and noticed die offs happening. I was also trying new foods like freeze dried chicken, dried shrimp and boiled carrots and potatoes.

I have since stopped feeding all those foods, but left the sand. There are still some dying though. My 2 tanks parameters are stable, so that shouldn't be an issue.

I am stumped...☹️

RIP Bob

Ahhh, poor Bob, bullied by the girls, but quite a big boy, Mauritanicus I believe, and nearly four months old 🙂. Survived by his last spouse, Susan, and about 300 eggs in the sand.

Trouble getting started

I’ve been trying to hatch tripod eggs for the last few weeks and having no luck at all.

I’m in the UK. My daughter got given a kids tripod kit for Christmas which we’ve tried to use without success. It was a ‘Swamp Monster Kit’ by Tarema.

We bought Highland Spring Mineral Water since this matched the reccs in the leaflet included. Small container, bit of white coral sand, set it up and put some eggs in - no hatching. Thought it’s probably too cold (old UK houses are built very well and water seemed to be about 17c. I also remembered that I’d got a small plastic tank and some sand I’d used for fish a long time ago.

Bought an aquarium water heater which heats to about 25c. We also got an angle poise lamp to shine on the water, which we’ve also put on a timer plug to be on 7am-8pm each day. So we setup new tank with sand and water and heater, waited for water to warm up for a day, added in old water (with ‘old eggs’) and sand to this tank.

No luck.

Added in rest of eggs we got with kit. No luck.

So now I have small plastic tank with water heater going to 24/25c, light for 12/13 hours a day with sand in bottom and Highland Spring Mineral Water, but no Triops!

Did I receive a bad batch of eggs? Am I missing something? (There seems to be a lot of conflicting advice on water types)

Should I clean it all out, refill with fresh, buy some more eggs and see if that works?

Thanks in advance for help. We’ve at this a while and researched and been methodical with no progress.
