Hi,

First I believe I should give the background of the sulawesi shrimp state before I purchase it.
The shop keeper state that he kept it in normal pH/gH/kH as all his fishes and shrimps.

The first batch of sulawesi I bought was a mixture of some harlequin and cardinal shrimps. I gradually adapted them to pH 8.0 with kH around 5 over a 2-3 days timing. However, after I introduced them to my main tank, a fair amount of harlequin shrimps died, however all the cardinals are alive and stable.

After around a few days, I decided to lower the pH down to around 7.7 and kH slightly lower (cant exactly remember). Cardinals started dying while all harlequin become stable for minimum of 1-2 weeks. Only when I decided to raise the pH and kH back to the recommended levels, harlequins started dying again (to none).

Therefore, personally I have this hunch that either harlequin shrimps prefer slightly lower kH and pH as recommended for cardinals. I would'nt say this information is totally reliable as this observation is only from 1 batch of sulawesi shrimps and does not conclude anything.

what did u use to reduce / increase the KH and ph ?

I used dechlorinated tap water (about 30min incubation) and adjust it with commercial products to adjust both the pH and kH. I'll suggest using a few corals to stablilize the pH and kH and have at least 2 x 1.5 feet tank as the shrimps are rather sensitive to water changes.


Currently, I've only managed to obtained 3 harlequin shrimps (Can't seem to find alot of them around). 1 died the night after i bought it, while the other 2 have been transferred to my 2 feet tank with substrates and corals, with O sea mud (for minerals lacking). They look stabilized for the time being.

Only difference from normal sulawesi setup is my kH and pH is abit different. Its still too early to tell anything, I'll update slowly once I managed to get a colony of Harlequin shrimp and managed to get them to survive for 3 - 6 months and see if any breeding is possible.

Thanks for the information!
