Suitable containers for keeping Triops

by Stuart Halliday

One of the great things about raising Triops is the low cost of keeping them.
Whilst some people keep Triops in aquarium tanks with fish, Triops are great at keeping the substrate clean as Triops will eat just about anything.

Others know that you just need something which will hold at a minimum around 2 litres (0.5 gallons) of water per adult Triops.

Basic requirements

Let's go through this list:

The container should not be toxic to the creatures.

The surface water area should be large enough to allow oxygen to dissolve into the water.

The volume of water should be large enough to allow the Triops to extract oxygen from the water.

Examples of Types of Containers
People have used plastic 5 litre still bottled water containers you can buy from your local shop and cut the top off.

People have used large glass jars that were used to hold jam or peanut butter.

Microwave or freezer food storage containers have all been used successfully. So your imagination is the real limit!

Next time you're in the supermarket, go down the kitchen ailse and check out their microwave food storage containers.

I find it fun to look around supermarkets for tanks in all sorts of shapes and sizes. Certainly makes food shopping more interesting!

I find this Tesco foodsaver 4.5 litre food container is ideal for keeping a couple of adult Triops. This type of container is very cheap at £1.10 (€1.57 US$2.00), has a lid and meets all the requirements mentioned above.

I cut a small hole in the lid to allow air to get in as placing the lid on cuts down on the amount of water which will evaporate over time due to its large surface area.

Take a look at the container page by Corne van Rensburg in our gallery for more ideas.

Tanks supplied with Triops kits
The various small tanks that are supplied with Triops kits are ultimately unsuitable for keeping a single adult Triops in. They are usually too small to allow the grown Triops to live out its life in a unstressed enviroment and really don't hold enough Oxygen in their small tank to keep one Triops alive and well, let alone two or three!

If you find your Triops are always floating around the surface of the water on their backs, they probably are Oxygen deprived and they do this to get more air to breath. Though of course Triops that do this from time to time are probably just feeding on food particles on the surface.

Why do the companies sell the kits with a small tank I hear you ask?

Well they want to keep the cost of the kit down, a larger tank means a bigger cost to the customer.

Some people have said that if the Triops all die after a week due to dirty water, over crowding or lack of Oxygen in the water then you've had your products worth and you may go out and buy another kit to try again.

Also most kits don't like to mention that if your Triops live at least a week then they'll start producing eggs and you'll not need to buy another kit as you'll have plenty of new baby Triops once you've dried the old tank out! So is it really in their interest to supply a bigger tank?
