    I noticed that shrimp gro has to be shipped 2 day. Is there special storage requirements in my home? Also I understand a pinch is all you need. Lets say you have 300 shrimp, how long should a large bag of the shrimp gro last, shortest, or longest time. I have changed their diet on some days, but let\’s say they are fed that excluselvly.
    Thanks
    Jeff

    Dear Jeff:

    Well, sir, it’s difficult to say how long a packet of the ShrimpGro will last you but I can certainly give you a rough guesstimate. If you start out with 300 shrimp, that number is quickly going to change because many of those shrimp will be gravid at any given time and giving birth to larval shrimp, while at the same time you will probably be harvesting some of the shrimp periodically to feed to your seahorses. So the shrimp population is going to fluctuate considerably from week to week.

    It also depends on the type of shrimp you are talking about. For example, because they are larger, ghost shrimp or cleaner shrimp will go through the ShrimpGro much faster than the very small Hawaiian volcano shrimp or red feeder shrimp (Halocaridina rubra). But assuming that you’re talking about the small red feeder shrimp from Hawaii, I would say a packet of ShrimpGro would feed 300 of them for at least a few months, and probably considerably longer. And if you include an algae covered piece of coral rubble or live rock or two so that the shrimp can also graze on algae, then the ShrimpGro can be stretched a whole lot further and may last you as long as a year.

    The Care Sheet with the storage instructions for the ShrimpGro is available online at the following URL, Jeff: http://www.seahorse.com/Aquarium_Life/Care_Sheets/Shrimpgro/

    This is what the care sheet states, sir:

    Ocean Rider ShrimpGro

    Sprinkle a small amount directly into your tank for your shrimp. This is an excellent high protein particulate food designed for feeding shrimp off all kinds including our Hawaii Volcanic Red Shrimp and amphipods. It contains very high levels of HUFA’s (long chain fatty acids), vitamins and minerals so free to feed it to everyone in your tank!

    » Please use a very small amount and be careful not to over feed.

    » Please store in a cool dark place (refrigerator or freezer is fine).

    Note that the instructions stress the importance of using only a very small amount of the ShrimpGro and taking care not to overfeed. A little of this stuff goes a long, long way and the worst thing that you can do is to use too much of it at once, which can degrade your water quality to the detriment of the shrimp you are trying to raise and feed. Use it sparingly!

    An unopened packet of ShrimpGro will last indefinitely when stored in a cool dark place, so you might as well order a couple of packets at once so you won’t have to reorder at any time soon and absorb those expensive shipping costs from Hawaii a second time.

    Red feeder shrimp or volcano shrimp, as they are sometimes known, prefer brackish conditions and breed best at reduced salinity (1.0145-1.0168) but they adapt well to full strength saltwater and will survive indefinitely is a marine aquarium. They are a perfect "feed-and-forget" treat for large seahorses! As a rule they don’t need a great deal of room. A simple sponge filter will do. The Care Sheet for the volcano shrimp is available online at the following URL:

    Here is some additional information about these shrimp, including suggestions for feeding them, that may be of interest to those of you who are interested in keeping or culturing these colorful little crustaceans:

    RED FEEDER SHRIMP from Hawaii (Halocaridina rubra)

    Pros:
    * Excellent nutritional value
    * Irresistible to all the greater seahorses.
    * Feed-and-Forget — lasts forever in saltwater!
    * Easy to enrich.
    * Simple to gut-load.
    * Can be cultured using simple techniques and the most basic setups.

    Cons:
    * Reproduces slowly; difficult to build up a large population.

    Collecting Tips:
    None.

    Culture Instructions:
    Specific gravity: 1.0145-1.0168; pH: 8.0-8.3
    Temperature: 68° F – 73° F (20° C – 23° C)

    These fabulous little feeder shrimp can be kept indefinitely in a spare 2-10 gallon tank, or even a clean, plastic bucket, that has been filled with clean saltwater and equipped with an airstone for aeration. Neither a heater nor a fancy filtration system is required. They thrive at room temp and reduced salinity (1.015-1.016), and all they require is an airstone (or a simple air-operated foam filter at most) to keep the water oxygenated, with perhaps a little coral rubble as substrate and a clump or two of macroalgae (sea lettuce, Ogo, Gracilaria) to shelter in. They’re easy to feed — they feed primarily on algal mats and bacteria — but they will accept vegetable-based flake foods and pellets such as various Spirulina products. They are filter feeders and can also be fed with yeast or commercially prepared foods for filter-feeding invertebrates. Many people find an easy way to feed them is to place a small piece of algae-encrusted live rock in their holding tank; once they clean it off, simply replace it with a new piece of algae rock. But if you want to culture them, I’d recommend ordering the special shrimp food formulated just for them when you order your feeder shrimp from Hawaii. It’s called Shrimpgro and is designed to meet all their needs and requirements:

    Comments:

    These tiny red feeder shrimp (Halocaridina rubra) are native to Hawaii where they inhabit underground lava tubes. Brackish pools collect in the cracks, crevices and depressions in the lava below the water table, thus forming the habitat for the shrimp. The brackish water that fills these pools consists of intrusive seawater diluted by freshwater that percolates downward. Because of their lava-tube habit, they are sometimes called Hawaiian Volcano Shrimp.

    Native Hawaiians call them Opa’e-ula, and they are unique among the several different species anchialine pond shrimp in being small, social, herbivorous shrimp that feed mainly on algae and bacteria. They are known to feed on insects that drown in the lava tubes. When conditions are favorable, they may feed en masse at the surface in swarms of countless individuals that turn the water red.

    Halocaridina rubra look like miniature, bite-size Peppermint Shrimp, and all seahorses save the miniature species go absolutely nuts for them! They are very nutritious and eat a varied, omnivorous diet. They are perfect for seahorses in every way.

    Unfortunately, it is very difficult to culture these shrimp in any quantity, since they reproduce slowly and the females only carry 12 to 14 eggs. They spawn but 4 or 5 times and produce an average of only 5-10 larvae per spawn. The larvae hatch as free-swimming, yolked zoeae after a brooding period of 38 days. Larval development is abbreviated with four zoeal stages and one megalopial stage occurring before they reach the first juvenile stage. Duration of the larval stages in the aquarium is 24 to 27 days at 22 to 23 degrees C.

    Like other shrimp, it is the complicated larval developmental period they undergo, with multiple zoea and megalops stages, that makes the larvae difficult to raise, Joe. However, it can be accomplished the same way other decorative shrimp such as peppermint shrimp (Lysmata wurdemanni) are raised. There is a very interesting and informative book that explains exactly how to go about raising such shrimp that I recommend you read. It’s called "How To Raise & Train Your Peppermint Shrimp" by April Kirkendoll and they can be obtained at the following URL:

    http://saltaquarium.about.com/cs/fprswaqbooks/fr/aafprpshrimpboo.htm

    You’ll find lots of excellent information on raising peppermint shrimp in April’s book that will apply equally well to your volcano shrimp.

    Best of luck culturing your feeder shrimp, Jeff!

    Happy Trails!
