Weird critter: Triops

Recently, my girlfriend thought about getting me one of those educational starter kits to hatch and raise triops. For those who don't know what they are (as I didn't until she told me), triops are an ancient crustacean that looks like a cross between a horseshoe crab and a face hugger from Alien. Cool looking critters.

You're supposed to hatch them in distilled water (the lack of dissolved organics signals the eggs to hatch).

So...I thought about getting a batch of these things and growing them in a container of some sort until they're big enough that they won't become fish snacks, then throwing them in one of my tanks to see what happens. I was just going to put them in my 20g and see how they fare.

Anyone ever kept these things before? Can they live in regular freshwater aquaria?

I have kept these before in their own container (<5G) back when I was 10/11 or so, but I remember them. You are correct with the distilled water hatching; when they hatch, you feed them very very small food particles, and it is survival of the fittest. You will have no more than 3, but most likely 1 or 2. They get to be a good size; around 2" or so (give or take).

I have no idea how they would fare in a home aquaria. I, personally wouldn't add them to the tank.

Well I have never heard of them and prolly for good reason. I don't like horseshoe crabs or anything even close to them! Long boring story. So anyway I looked them up, and as I suspected they are EVIL , lol, no, they are tiny but still to crabish for me. I saw somewhere where there is a guy who said he keeps them with his fish and he even had pics. From what I read, they only live about 8 wks, though.... but they do usually lay more eggs. And to hatch those, you have to take them out of the water, dry them out for a few days, and then add them to water again to hatch them.... , idk, sounds wierd. Speaking of wierd, did u know these thinga have 3 eyes??? And 140 legs, and they breathe thru their FEET!!! , good luck with tem, I'll pass , o and the website is if u look under gallery its where they had the pics and a video,...other than being creepy though they are suppose to be lots of fun to watch...doing backflips and such!

Very fascinating little critters. I remember my niece raising some for a school project and she was quite taken with them.

I'm not sure I would want to put my hands in the tank with something like that crawling about the bottom though

I can't find anything to indicate they would be harmful to fish.

The page showed pictures of triops living with dyed glass tetras, gouramis and angels, so I guess they're fish safe. I was just worried because they will apparently eat one another if food is scarce. Maybe I'll give this a shot afterall.

Too bad the stupid critters don't live longer...they're really interesting.

they dont live long because they come from sess pools or however you spell it okay they live in temporary sess pools which eventually dry up and the eggs stay there motionless till the next rain shower comes thats why...they adapted themselves to it

ive tried to have triops before but something weird also happened to me. I ended up with like 2 horseshoe crab like things and then like 4 really creepy white shrimp-like creatures with tons of swimmerettes and those were like really active and all over the place. They were kept in a jar and eventually the water got so dirty cuz i was too freaked out to change teh water that the water turned a muddy brown and goo formed at the top. However, at that time u could still see the creatures inside whent hey got close to the glass. My mom flushed them randomly one day and taht was the end of it. Note, i was like 9 when this happened.
