Thanks!

Yip I have cheato in the breeder net. The problem I have with the locally caught Mysis is not keeping them alive, (they stay alive in round aerated buckets for more than a week), but die within 20-30 seconds after introducing them to the rearing tank's water. Like I've mentioned, I have not been successful in aclimatising them to the warmer water. Also the locally caught Mysis are more than double the length of the new born cuttle. I'm starting to stress out!!

Oops, we have a couple simultaneous new cuttle threads going and I miss-ided your last post when replying :dig:. Can you get something called a "tiger" pod there? I have little hope that they will work but have seen them used in conjunction with mysis with success. Once they start hunting and eating, they can take down the larger prey but getting to that point is a major hurdle.

When you have collected the mysis, are there other, smaller animals in the tow? Adding a brine shrimp net filtered plankton tow has not been tried (or at least reported and you risk adding unwanted bacteria or other things to the tank that may be undesirable) but might be worth a last resort effort.

Thanks, DWhatley !

Nope, nothing else in the net when catching Mysis. Some of the Amphipods/Grasshrimp I have are tiny though (0.11 - 0.19 inches, and shrimp 0.40-0.60 inch).The problem with the pods are that they all climb out of the breeder net. Looks like I'm going to have to go scratch around rock pools and under rocks to see what I can find. Will also try a finer net in the spot where I catch the shrimp. This is soooo frustrating !

A. my advice can hardly be construed as expert, but thank you very much.
B. they are climbing out?? that's a new one to me. mine zip all over the place and hang onto the net, but seem to be relatively content to stay in the water.
C. amphipods come in a variety of sizes. the ones i collected are very small and the newest ones are probably 2-3mm in length and the cuttles I've kept have had little trouble mastering them.

Are they climbing out to get to air? Some pods are terrestrial and get their oxygen from the air...

Hi All !
Thanks for the replies. Yip, the Amphipods (95%) climb out of the water, but a few hide in the Cheato. I've now added a piece of dried seaweed to the net breeder in the hopes that they will swim down to have a munch, but no luck so far. I'll be collecting some Mysis again on Friday with our local Public Aquarium guys, to see if the cuttle will be able to catch some before they die (previous experiment they only stayed alive for 30 seconds after adding them to the warmer tank water). I'm not going to give up !

Thank you.

I'm seriously worried ! None of the hatchlings are eating. Tried amphipods, small shore shrimp, and mysis (like I mentioned, the mysids die too quickly). Tried more current ( as was suggested by cuttlegirl), to keep the dead mysids moving, no luck. This is sooooo frustrating.

The only suggestion I have is to keep trying as sometimes they don't eat immediately and often eat at night. If you are keeping the mysis alive in a separate bucket, be sure to add some after dark.
