Triops Longicaudatus prehistoric crabs with about 150 eggs incl. food This type of Triops can reach a size up to 9 cm. They are very agile and swim merrily through the aquarium. After about 2 weeks, they reach sexual maturity and begin to lay eggs into the sand. At the picture you can see small red beads. These are the eggs. The Triops at the picture is 3 weeks old and it has got a size of 6 cm. So you can imagine how fast they grow. Triops Longicaudatus will reach an age of about 7 to 12 weeks. During this time they put a lot of eggs for a new breed into the sand. To prepare, you only need a small container with about 2 liters volume and some distilled convenient fishwater. If they reached a size of about 10 mm, you just have to resettle them into an aquarium. Then you only need to add aquarium gravel, thats it.The rest, as pump, snails and plants, can be arranged but there is no need for it. Its just an optical upgrade. I will give you a mixture of eggs and sand, about 150 eggs. You will also get an insightful rearing manual with details ( watch out for emails from me ) ,some dust and some staple food for the first few days.
