Water parameters, molting, and species guides.
The cardinal shrimp in your tank, or the one you’re about to order, keeps turning up online with “extinct in the wild” next to its name. Sulawesi shrimp aren’t extinct in the wild, and no Caridina species sits in the…
Can two kinds of Sulawesi shrimp in one tank really produce hybrids? Yes: they’re separate species, but that doesn’t stop them mating once they share water. The conservation group Sulawesi Keepers has published breeder accounts and photographs of crosses between…
There’s a fresh shell lying on the rock, and two males have suddenly started darting across the glass. Those are two of the four signs that Sulawesi shrimp (Caridina spp.) are mating: a freshly cast shell, a short burst of…
Why is everyone after Sulawesi White Sock shrimp? Three reasons: their red and white look is pure wild color, they graze in the open once they’ve settled, and they’re known as the most forgiving Sulawesi lake species. White Socks are…
Are Sulawesi shrimp actually endangered? In the wild, yes: every Sulawesi shrimp in the table below carries a current IUCN Red List assessment in a threatened category, five as Critically Endangered and two as Vulnerable. One of the five, the…

Every page you check seems to give a different number of Sulawesi shrimp species, because each one is counting something different. If you mean the lake species the hobby calls Sulawesi shrimp, it’s about two dozen, out of 62 atyid…
Do you need to pull the males out of your Sulawesi shrimp tank? Usually not: a colony that already holds more females than males rarely needs anything netted out, and removing males only helps once a group has drifted male-heavy.…
You’ve got RO water ready for a Sulawesi tank and two SaltyShrimp salts to choose between, Sulawesi Mineral 7.5 and Sulawesi Mineral 8.5. Neither is better in general: they land at opposite ends of the same pH 7.5-8.5 target, so…
Which filter should go on a Sulawesi shrimp tank? An air-driven sponge filter, or in a larger tank a matten filter, which is a foam wall with an airlift behind it and the same idea scaled up. Both put biological…
Your tap water reads somewhere near the Sulawesi range, and an RO unit looks like one more thing to buy before the shrimp arrive. Sulawesi shrimp, the lake-system Caridina species traded as Cardinal, Sulawesi White Sock, Sulawesi Blue Ghost and…
