Main rules to hatch triops:

Use bottled water (still natural spring) or rain water. Do not use tap water as it may contain chlorine that is toxic to Triops. In order for Triops eggs to hatch, the water needs to be at a constant temperature between 21° - 27° C   degrees and have at least 12 hours of light a day. In the summer months no artificial heat or light is required but in colder months you may need to use a desk lamp to provide extra heat and light. Feed your Triops on day three. If you have the pelleted variety food, crush it into a powder between two spoons and add a very small pinch. Repeat this every other day. Too much food could kill your Triops, so if you notice any uneaten food at the bottom of the tank do not add more until it has gone. Please be patient and always wait 7-10 days before deciding that your attempt was not successful.

What are Triops?

Triops are crustaceans. The crustacean's family includes animals such as shrimps and crabs. Triops obtain oxygen they need from the water through their feet and this characteristically places them in a group of crustaceans called Branchiopods. Your Triops scientific name is Triops Longicaudatus, but their common names are 'Dinosaur Shrimp' or 'Tadpole Shrimp'.

What do I feed Triops?

All the Triops kits come with Triop food (shrimp food), however, you can feed your Triops on a good quality fish food (use granules, not the flake variety) available from aquarium or pet shops. Triops will also eat tiny amounts of grated carrot.

Can I change the Triops water?

Yes, you can. Carefully pour away some or half of the water. Then top the tank up with clean bottled/spring or rainwater that has already been raised to room temperature. This can be repeated several times if you are not satisfied with the clarity of the water. It is a good idea to repeat this process at weekly intervals.

Where can you find Triops?

Different species of Triops can be found in every continent. Your Triops come from the USA, where they are more commonly found in desert areas. They live in small ponds that exist only for short periods after it has rained. Because the water soon dries up the Triops need to hatch, mature and reproduce quickly so that their eggs will remain when the pond no longer exists.

How long do Triops live?

Once Triops eggs have been added to water they generally live for approximately 6 - 12 weeks. Triops are known as 'living fossils' because they first appeared on earth 350 million years ago and have a striking resemblance to the now extinct Trilobite. It is thought Triops have been able to survive on Earth for so long because their eggs have the ability to enter a state called diapause. This means they can remain dormant for many years (even decades!) until they are re-hydrated (added to water) and hatch. So, if there is a long period of drought or freezing the eggs will survive until conditions become more favourable.

What is a Triops life cycle?

When Triops first hatch they are larvae, but they quickly moult to become young tadpole shrimps. They often double in size every day and can grow up to 4cm in length. They are capable of producing eggs when they are 2 to 3 weeks old. If you have only one Triop you still may be able to get eggs. This is because most Triops are hermaphrodites; this means they can fertilise their own eggs. The hermaphrodites have a pair of white brood pouches, which carry the eggs and are located between the upper legs.
