Before you decide to breed this rare kind of fish, it is always a good idea to ask your regional vet the sex. You can always try and breed them yourself but this can turn out to be a challenging task for most. Usually the male Triops Longicaudatus have large pads under their finger, which allows them to grab onto the females for mating purposes.
Consider putting the males and females in the same setting. They can actually stay with each other without resulting in any risk to one another. These Triops Longicaudatus will not eat each other unless they are starving to death. Therefore, it is advised not to separate them. It is actually a better concept to have 2 females and 4 mates in the fish reservoir.
Put the fish reservoir in the underground room for about six to seven weeks. What we are trying to do is introduce a cool down interval which will start the breeding process. However, make sure the temperature is not below 45 degrees Farenheit so the Longicaudatus do not die. Once the six weeks have gone by, consider increasing the heat range progressively.
For those looking into breeding this rare kind of fish, you should observe them throughout to actually see if any improvement can be seen. Typically, a male will try and capture the female from his fingers and then jump onto her back for mating purposes. If she remains in that place, it is an excellent signal, suggesting that the breeding process has begun.
Once the breeding process is over, it is the time for the females to lay eggs. She should lay about 200 eggs on the bottom of your fish reservoir or also around any rocks placed inside the aquarium.
Once the eggs have arrived, consider separating the male from the female. Separate the eggs carefully and exchange them into another fish reservoir. However, you must make sure the reservoir is at exactly 77 degrees F. The eggs should hatch out in approximately three to four days time.
