Breeding Tigger pods

I have some tigger pods that i picked up today at a lfs. I was wondering if anyone had any success breeding them.

Some are in my refugium, I left about 1/2 the bottle (in the bottle).

It says on the bottle that they will last longer if you refridgerate them? I read some post that folks had more success breeding them at warmer temperatures? I put a little bit of cyclops eeze or whatever that is called in the bottle and left the lid off, it is in a dark environment as I dont want algae growth to be too much of a problem....any ideas

Thanks!

I find that they really prefer the cooler water temps , which I've read since tring myself. I added some to a 2.5 tank with just live rock and cheato but they disappeared over 3 days with nothing eating them. I find it hard to believe that a tropical species deals well with refridgeration let alone be highly active. Perhaps a unheated tank/bin with air tube and feed phyto or other filter feeder food. Do watch changes by using a flash light to attract all to one side and siphon with a brine shrimp net over the tube or strain into a micron filter. Mind you this is how I raised daphnia and all the stuff I've read about pod/rotifer culturing seemed pretty much the same.

Tigger-Pods (Tigriopus californicus) will NOT grow well in your main display tank. They don't instinctively hide from fish, are very large easy to find, and they often starve in reef systems because there is not enough microalgae for them to feed on. They grow best in your refugium or simulated tide pool (a 9x13 cake pan works perfectly!).

 

Tigger-Pods commonly live in tide pools and range from Canada to Honduras, from very cold water to very warm water. They are definitely not just a "cold water species". Due to their wide temperature tolerance they can be stored in cold hibernation for up to 8 weeks, hence why they are kept in the refrigerator at your local fish store. Hibernation reduces their need for oxygen and food, and extends their lives.

 

Their optimal growing temperatures depends on where the broodstock were originally harvest. Our broodstock population was collected in California where tide pool temperatures can approach 100 F so they are acclimated to temperatures at or above reef system. We've been culturing them at 75-90 F for over 6 years.

Tigriopus californicus don't live in the ocean - they live in the warm splash zone pools up above the ocean. These pools are shallow and get quite warm during the day, some much warmer than reef systems. The following published scientific study shows that they live in temperatures ranging from 42 to 92 F:

In these tide pools there are no predators so they don't have the instincts to hide in the rocks when fish come by. Since they don't hide they get eaten pretty quickly in display tanks. We recommend they be cultured in a sump or refugium where there are no predators. They can also be easily cultured in a separate system like a 9x13 cake pan.

 

The population of copepods in a reef system is often food limited by the amount of natural microalgae that the reef system produces each day. When additional pods are added the food requirements immediately goes up, especially when feeding very large copepods like Tigger-Pods. Unfortunately many people don't realize they need to supplement with microalgae so both the Tigger-Pods and the existing copepod population end up with a food shortage and quickly starve.

 

The analogy I use when I'm giving presentations is "If you have an acre of land that produces enough grass to support one cow but want to have lots of cows - what do you do? You add bales of hay and suddenly that 1 acre will support LOTS of cows".

 

Microalgae is like hay to your zooplankton. The more you add, the more zooplankton you will have. If you don't have enough, they starve and disappear.

wow! that is cool. next time i will try the pan culture. that makes sense, i have a fish that has been picking some (alot) of them off. They just kind of float around aimlessly and appear to be easy prey as you mentioned. learning experience!
