DAS are very robust and I've kept them in a tank with Melbourne tap water and in rainwater with DIY hardness booster. You'll find them in Northern Australia in both the fresh and brackish sections of rivers so they have really wide tolerances. My tanks range from 24C to 29C
If you get some keep the covers on for the first 2 weeks as they can be jumpy if your water parameters are a long way from what they were housed in. After a couple of weeks they settle down and rarely jump. I know some people with open tanks put gladwrap over the top for the first couple of weeks only.
I'll also suggest that no-way will they interbreed with your Tangerine Tigers - they are very different shrimp and their bits wont fit together even if they were so inclined.
Idk my tds but the rest sounds similar to my tap. If Grubs uses just dechlorinated tap water too then we probably would have the same parameters as we’re both in melb. And that’s my normal temp as well.
How do you keep them @Grubs?
I would get a few if you like them, the odd loss of a baby shrimp wouldn't really be a problem. There are lots of shrimp people that have the dwarf Corys with their shrimps.As you say, it maybe better to wait a bit until you have more shrimps first but the cory doesn't hunt shrimps as food!
I think that the shrimp in the photo is a female!
Great you got the slots sorted so quickly and easily.
The good thing with the amano is that they won't breed so you will never get more than you buy. Don't get too many though (may be the 5) as they are bigger and will out compete the cherry shrimps for food. Don't forget that there is postage cost with ProShrimp below £39 (I think that is the figure??) so bear that in mind as if you are close to that and you buy a few more shrimps you will get more shrimps for the same cost by not having to pay postage - f that makes sense? The other option is the tangerine tigers as they won't cross breed with cherry shrimp but you get a different colour - those are out of stock at the moment though! You need to be at home next day to sign for the package.
No nothing special. Just get them the right water parameters and that's it.
@Grubs might have the perfect water parameter requirements for DAS, so see if he can list them.
Otherwise, I used to keep DAS in water that was ph6.8 - 7.0, KH 4, GH6 and TDS of 200-230 and 25DegC.
These shrimp from QLD seem to handle slightly higher temps.
