Hi, as the title says I'd likt to breed these...so every scrap of info avalible would be useful! :)
 
It's very easy :).

Just set up a tank for them with males and females, and cover the filter inlets with sponge (preferably just use sponge filters) to protect the babies and thats it.

Just need to make sure the tank is stable, no traces of ammonia or nitrite ever.

Growing plants with them goes a long way to help.
 
So as long as I have a decent mix of M-FM, mature and stable filter and water...avoid PH, KH extreams they should breed?
Also what size would you suggest for a large colony?
Any specific foods to help them breed?
:rolleyes:
 
Yup. They are also very sensitive to copper and meds, so it's good to have carbon on hand and put in the tank if they shrimp ever look not quite right.

Depends on what you call large, but 10-20gals would be ideal. Obviously the bigger the better.

Best foods would just be a balanced shrimp food, basically any brand made specifically for shrimp. They can thrive on most fish foods though. Giving them blanched spinach, romaine lettuce, slices of courgette every now and then is also good. But mainly just try to provide a natural environment with lots of plants, bogwood, debris and leaves.

The most important thing is for it to be mature and stable, but making it as natural as possible and feeding only a little food is the best way to go so the adults can constantly forage and the babies can find natural food. This is where the plants come in, they allow you to keep the tank naturally "dirty" while avoiding too much algae and always getting rid of ammonia for you.

So for best results (heres what I do), use some fairly strong lighting, add some boiled oak leaves add a load of very easy plants(mosses are great, but fast growers like Hygrophila polysperma are more useful for keeping the water clean) and use an air-powered sponge filter. The stand-up type that you can put carbon in the middle would be best*. Dont use an air pump that's too powerful, more surface disturbance = less CO2 in the water = slower growing plants. Floating plants are great, since they can use CO2 from the air, they will grow very fast which is great for the water.

You can use a power head attached to a lot of sponge filter styles, but just make sure you dont get a powerhead thats so powerful the sponge has a lot of suction. If you choose to use a powerhead (which can be better, less surface disturbance = more CO2 in the water and better circulation), go for a bigger sponge filter than needed, so it doesnt get clogged up too much and things areless likely to be sucked in.

Set it all up, and I would add some mulm, filter squeezings or dirty substrate from a mature tank at this time too. Leave the tank for a couple of weeks for the plants to grow and for the tank to settle a bit. Then put a few nice shrimp in, 6-10 would be good, but more is OK. To be safe I would put a little carbon in the filter just before you add the shrimp, and take it out a day after. Just in case there was any residual copper on the plants or other contamination.

Expect algae if you went for strongish lighting (~2WPG of fluorescent). There's nothing wrong with the algae except it doesnt usually look nice. Shrimp love it, they can eat it, and at the end of the day the algae is cleaning the water just like the plants. Over time as the tank becomes mature and the plants get well established, the algae will dissapear, but this can take months.

Keep the lighting on for 7-12 hours a day, and the temperature 23-24*C.

Not many water changes are needed, little 10-20% ones every few weeks are a good idea to replace some nutrients, but mainly just top up the tank for evaporation with distilled, RO or very soft tap water with a decent dechlorinator.

Do test every few weeks just to make sure the water isnt getting too acidic or anything, adding some crushed coral/calcium sand/shells or the like under the substrate is a good way of avoiding this.

Feed the shrimp every 1-3 days, but once it's mature they can go longer without the food, the food is mainly just replacing nutrients used up by the plants.

You can add small algae eating fish, but do choose your species wisely (generally, some common things like ottos aren't suited to this kind of set up) and remember to make sure they are getting enough food without over feeding with algae wafers (this is much easier once the tank is nice and mature).

Once the shrimp population is booming, some nano fish like dwarf rasboras or ember tetras would be a great addition too.

Hope this helps :).
