The majority of the shrimp we keep are of the decorative and cleaner types, all of which I feel can have a place within our reef tanks, besides being functional in providing fish and tank cleaning services along with pest removal, they are very interesting to watch and add a nice splash of color to the reef.
There are many species to chose from such as the peppermint and fire shrimps along with various anemone/clam hosting shrimp. One popular species deserves mention, the coral banded shrimp, far to often I hear of it being a "killer", which may be due to our misunderstanding their needs. They, as well as a good many other shrimp species are territorial. If other shrimp are kept within to small of a tank, there an be problems. There are other species available that are not much to look at but are very functional in their clean up service such as the Saron shrimp. Care must be taken with all shrimp types in providing good water quaility and no sudden changes. As with all invertebrates, having elevated nitrate/ammonia levels will cause them great stress and should only be introduced to an established, mature aquarium.

If you have shrimp or any other animal that is actively spawning in your system, I feel it is our responsibility to take the effort of trying to rear such animals and provide them back to the hobby. With the amount of animals that die within our care, the collection of wild specimens to replace them is a great strain on the wild reefs. You will most likely find that in doing so, you will greatly enhance the enjoyment of our hobby as well.

Since I live on a fairly remote island, or at least one that does not have any reef equipment or something as basic as acrylic, I have had to improvise the building of a kreisel tank if I was to have any success at all with rearing shrimp and other larvae. As such, as you can see in the above photo, it was not all that difficult to do. I had a custom aquarium built at a glass shop that was initialy three compartments, the left one taking up half of the tank while the right side was divided into two other compartments. For the kreisel section, I used a piece of acrylic (had to buy a picture frame and cut it up) to form another divider to create a pump and aeration area as well as having a screen mesh installed.
For the mesh screen, you can try other material such as micronfilters, but I have found that cutting up a simple pair of lady's nylonstockings works very well. I do not have a clogging issue and the larvae and copepod food can not pass through. The baffles shown are simply small peices of acrylic cut to fit snuggly and siliconed into place. The powerhead was the smallest one that I could find (50 litre per hour) since you do not need a strong flow to create a gentle circular current within the kreisel section. The above photo shows a bit more detail of the bubble trap I use on all tanks that require an airstone for aeration. For more details on how to construct one, please see my Air Stone Bubble Trap webpage.
A few tips on creating your own Larval rearing station : - You can use any sized aquarium that you wish, although the smaller ones such as I have used are easier to work with and their needed water changes do not require a great deal of water, maybe a gallon at the most. - Get a small powerhead and one that has a flow valve since even with such a small powerhead, I have to turn to flow valve to just above the shut off point to get a nice gentle flow going. - Make the hole for the mesh screening as large as you can, this allows a much slower flow to go through the mesh which prevents any larvae from being pinned against the mesh by a higher flow rate. A small opening would force the water to blast through it. - Make the divider peice a bit lower than the top of the tank. If the mesh should become clogged, the water can overflow the top of the divider back into the pump area and avoid having the tank overflow and flood the house.
