Hawaiian red shrimp in lower salinities

[Koi Kameon]

I've read their optimal range is 1.008-1.012 or 15. Has anyone kept them at or heard of them being kept at 1.005 and being healthy?

To be honest, I got pissed and tired with waiting for them to get berried. So I tried varying the salinity. I've even kept them in freshwater for over a month with no casualties, but I'm not sure about longer times than that.

Somewhere else I am pretty sure that I remember a native mentioning that someone they knew in Hawaii was keeping some in a barrel of pure rain water - though they mentioned that while they seemed to survive and grow just fine they were NOT breeding in that environment.

Wanted to let you know the reason I asked--setting up low brackish tank to 1.005 and found a list of about 20 plants that would live in it. The obvious like all the java ferns and the japanese moss ball, to the not-obvious--african tiger lotus?? So, it got me wondering...The five listed for higher salinities were java fern for up to 1.0123, java moss up to 1.010, japanese moss balls at 1.009, and anachris (E. densa) at 1.008, and Cryptocoryne ciliata at 1.009. The list was on "Tropical Fish Forums" under "planting a brackish aquaria." I don't have the link bc I printed it out and it just gave the print info. when I did that.

There are not plants in the anchialine pools that the Opae Ula live in (or so I have heard).

Still, plants that could survive in an Opae Ula tank would likely benefit them since they rely so heavily on micro-fauna, algae, etc. and because the plants would provide filtration and most people try to avoid strong current or strong mechanical filtration in Opae Ula tanks.

Let us know how it turns out.

This is very interesting. I can't wait to see how this turns out. Be sure to post up some pictures

I don't know if I will wind up putting them in there or not. Have had them a long time now and would hate to mess that up. Re: ponds. I saw a pic of the Fuku-bonsai guy next to one in a jungle-like setting. I'm pretty sure it was in the brochure I bought from him on them. But there were things everywhere that could fall in there--branches, dead leaves, etc., plus I'm sure there have got to be some Hawaiian plants that like those pools too besides algae. Of course, not java ferns, moss balls, etc.

I don't see how the plants would hurt anything.

Mostly just warning you that some biotope purist would probably happen along at some point to raise the issue.

[Koi Kameon]

Yeah. I know.

decided to bag the idea. if i change mind will post results. they are just too settled in their current home.
