marine iodine
Hmm, I'll need to get some of that (will it affect my bettas?)
Nice shrimp calla!

They hide underneath the d-wood most of the day when the light is on, but when it turns off they seem to come out a little

Thanks everyone

Adding a small amount of marine iodine has been proven to help with molting and increase the survival rate of shrimp.

I'm sorry to say that I must disagree - there is, admittedly, no empirical evidence to the effect that freshwater shrimp can even metabolize aqueous iodine, and my personal experiences lead me to concur. However, I would be intrigued to see a long-term controlled experiment centered about the utility of such additives to be conducted.

have urs bred calla? they're the ones if your 3footer right?

While fertilization, presence of regularly ovigerous females, and even release of planktonic young are far from uncommon occurences, the latter require water of brackish salinity to develop into benthic post-larvae (essentially, miniature adults). If you wish to rear any P. australiensis larvae to maturity, I suggest following standard procedure for the Amano shrimp, C. japonica, as detailed under the 'Breeding' segment here.

I've heard from several people and companies I've ordered shrimp from that they've lost alot fewer shrimp do to molting complications when using iodine. Using it over a year many people said they'd lost 1/4th as many shrimp as when they didn't use iodine. Unfortunately I haven't found where anyone has done a true experiment with shrimp and iodine. In my searches for care info most sites seem to recommend at least a few drops of marine iodine monthly. So far I haven't lost any of my shrimp since I added them 10months ago. There are around 1 dozen rainbow shrimp in my 55g, 2 ghost shrimp in the 5g, and 4 ghost shrimp in the 20g.
