Welcome to the start of my Triops page. Rather than reinventing the wheel on care instructions, I'll just document my own personal experience raising these fascinating creatures. For detailed information, visit mytriops.com. My Triops eggs were purchased from discoverthis.com, and I'm quite happy with that vendor. Specifically, I purchased the Starter/Refill Kit. The eggs are of the Triops longicaudatus species, and have proven to be Very fast-growing.


Before starting the eggs, I went out and purchased everything I would need for the entire generation: 10-gallon aquarium set with under-gravel filter ($30 USD), 2 litre plastic beta tank ($12 USD), distilled water ($2 USD), Spirulina flake food ($1.50 USD), aquatic plant ($1 USD), gravel for the 10-gallon tank, some plastic transfer pipettes, and a reliable underwater heater for the 10-gallon tank ($13 USD). The beta tank is heated by an overhead 75watt bulb, suspended approximately six inches above the water surface. I set everything up (using treated water in the 10-gallon tank), and let it cycle while the baby triops grew to be large enough for their eventual tank upgrade.

Raising, and Use of Tanks

While the raising of the first generation was quite straight-forward, I had to take a risk on the second one. Newly released eggs started to hatch, so I moved them into the beta tank with a transfer pipette. This ensured that they would not be cannibalized by their parents. In order to compensate for the fact that the infusoria nutrient pack had not been in the water long enough to populate the beta tank with edible microorganisms for the babies, I moved about .25 litre water from the top inch of the 10-gallon water column. I understand that most of the single-celled algae collects up there, close to the oxygen and the light from above.

PH, Amonia, Nitrite, Nitrate

I learned the hard way that a new tank _must_ be sufficiently cycled. My entire first and second generations died off due to spiked nitrate levels. I discovered this by finally buying test kit for nitrate, as well as kits for PH, amonia, and nitrite (all three of which can be killers of aquatic life forms). While PH, amonia, and nitrate were all okay, it was the nitrate which thinned out and ultimately eliminated my poor Triops. You'll see that the first and second generations are far lower than what they should be. Had I succeeded, these would be closer to 35 days. I strongly recommend you obtain these four test kits and err on the side of caution when introducing your baby Triops into the larger tank. If your nitrate does spike, it's probably best to move your Triops into a different body of water until the issue has been resolved. Even major water changes did not quickly lower it. I ultimately stimulated algal growth by increasing light and aeration in the tank. It turned very green for several days, during which I continued to do 50% water changes every two days or so. By the sixth day, the nitrate was dropping quite rapidly.


Once they are in the 10-gallon tank, I found that Hikari brand food pellets worked very well for feeding. I snapped the sinking algae wafers into smaller pieces and spread them throughout the tank. On occasion, I would feed two or three carnivore pellets in place of the algae wafers. I found it necessary to allow them time to soak up enough water such that they would sink when squeezed a little between thumb and forefinger. It seemed that they were more likely to eat when the meal alternated between these two diets, but I may have been imagining this.
