I am the founder of Shrimp Aquatics and a freshwater aquarist with 4 years of hands-on experience keeping and breeding ornamental shrimp, fish, and invertebrates. Based in Ho Chi Minh City, one of the world's leading hubs for aquatic livestock, I test every care guide in my own fish room before publishing.
Care-guide methodology: husbandry advice is checked against observations from our own tanks where applicable, while species and water-parameter claims are reviewed against cited sources. Read our Content Policy.
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…
Neither one is better in general. Sulawesi Mineral 7.5 and Sulawesi Mineral 8.5 are built to land at opposite ends of the same pH 7.5-8.5 target. So choose by which end your filter, your equipment and your weekly routine can…
For a Sulawesi shrimp tank, the default filter is an air-driven sponge filter. A matten filter, which is a foam wall with an airlift behind it, is the same idea scaled up for a larger tank. Both put biological media,…
Sulawesi shrimp, the lake-system Caridina species traded as Cardinal, White Sock, Blue Ghost and Oiran, need RO water because it’s the only starting point you fully control. A reverse osmosis unit pushes water through a semi-permeable membrane and splits it…
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)…
In our tanks, young Sulawesi shrimp molt more often than adults, and a water change often sets off a round of molts. The one to two week interval you’ll see quoted for adult cardinal, white sock or blue leg shrimp…
For most keepers, no. A Sulawesi tank is held at 79-86°F (26-30°C) and pH 7.5-8.5, and that combination works against aquatic plants twice over. It leaves almost no free carbon dioxide for them to photosynthesize with. It also turns any…
KH is the carbonate reserve that decides how far your pH moves each day and where it settles when it stops moving. In a Sulawesi tank you’re asked to hold pH 7.5-8.5, which is well above where most freshwater naturally…
No. Sulawesi shrimp don’t need frequent water changes, and a fixed weekly schedule is one of the easier ways to destabilize a colony. In a mature, lightly fed tank the useful routine is replacing evaporation with pure RO water, testing…
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…
Losing one or two Sulawesi shrimp a day, day after day, is a different problem from losing most of the colony at once. A steady trickle points at a condition the tank has drifted into, one the shrimp can hold…
No. Compared with other freshwater shrimp, Sulawesi shrimp are one of the least forgiving groups in the hobby, and typical difficulty for the group runs advanced to expert. The daily routine is light once a tank is mature, but the…
