Mating, eggs or live birth, raising young and breeding problems.
Read what the female left behind first: it tells you more than any single cause you could guess at. Eggs sitting inside a cast shell, loose eggs on the substrate while she is bare, and a clutch that thins out…
Yes, they can. Sulawesi shrimp are separate species, and that doesn’t stop them mating once they share a tank. The conservation group Sulawesi Keepers has published breeder accounts and photographs of crossings between Sulawesi lake species.[[1]] They include a hybrid…
You’ll almost never catch Sulawesi shrimp (Caridina spp.) in the act. What you get instead is a short chain of indirect signs: a freshly cast shell on the substrate, a sudden burst of searching by one or two males, sometimes…
You don’t have to remove every male Sulawesi shrimp, and a colony that already holds more females than males usually needs nothing netted out at all. Males matter for one reason. Mating is timed to the moment a female finishes…
Care sheets say three to five months, and some say four to six, but none of them cites a study that timed a Sulawesi shrimp from hatching to its first brood. One published rearing trial on cardinal shrimp (Caridina dennerli)…
A female Sulawesi shrimp carries a very small brood. Published counts for the lake Caridina of Sulawesi mostly fall between about 12 and 30 eggs at a time[[1]][[2]], and the highest figure recorded for any of them is 26 to…
If your Sulawesi shrimp are alive but nothing is reproducing, the cause is almost always the tank rather than the animals. In most stalled systems it’s one of four things: water that drifted out of range or moves too much,…
Sulawesi shrimp eggs, from lake Caridina such as the Cardinal shrimp (Caridina dennerli), usually hatch about three weeks after the eggs first appear. The female carries the whole clutch under her tail until each egg hatches directly into a tiny…
