First, prepare a small tank. It can be 5 gallon but if you have a bigger one that is OK. It must become a shrimp only tank. Snails are OK.
Add an aged sponge filter.
Add a heater set for between 70 and 75 degrees F. If you don’t want to do this you can leave the tank at room temperature if your room is above 60 degrees F. With colder tanks, the shrimp won’t breed as fast if at all but they will survive just fine.
Add whatever plants suit your fancy. The only important thing is there are plants. Even cheap floating plants such as hornwort are good.
Add light. I put a 5 watt LED floodlight on the top. Anything in the visible spectrum will do as long as it grows plants. More light would be better.
Let the algae grow … the more the better!
Wait 2 weeks.
If the algae is growing, get a dozen of the nicest shrimp you can afford. Cherry shrimp are the least expensive if you don’t want to spend much. I happen to think if you are going to go thru the trouble to raise shrimp, you might as well raise the best.
It’s important not to mix Neocardina species as they will produce hybrids. Even mixing colors of the N. heteropoda is as liable to produce bad results as good results unless you know what you are doing.
Feed sparingly. Make sure they completely eat what you feed them before feeding again.
Wait six months.
Start selling or giving away the culled shrimp to your new found friends. Always keep the best for breeding.
