Every guide we’ve written on keeping Sulawesi shrimp, covering RO water and KH, feeding, breeding, tank mates and what to check when shrimp start dying. Setting up your first Sulawesi tank? Start with the beginner’s guide. Already have shrimp in the tank? Sulawesi shrimp care parameters lists the water numbers we keep to and how to hold them steady.
Sulawesi shrimp (lake Caridina species) are kept in warm, mildly alkaline water with a modest mineral load. The practical way to hit that is to start from RO or RO/DI water and build it back up with a mineral made…
Sulawesi shrimp are demanding, but the ways a colony goes wrong aren’t mysterious. They trace back to a short list of decisions taken before the shrimp ever arrived: an active soil working against the pH, mineral that never fully dissolved,…
No water change interval has ever been measured or published for Sulawesi shrimp, the lake endemic Caridina species from Sulawesi’s ancient lakes. Every figure in circulation, from 10% a month to 30% a week, comes from keeper practice. What actually…
Choose Sulawesi hardscape on two questions. Does the rock change your water? Does it hold a film the shrimp can graze? Inert volcanic lava rock answers both, which is why it’s the working default in this tank. Carbonate rock fails…
You raise pH for Sulawesi shrimp by rebuilding the water outside the tank and exchanging it in slowly, not by dosing the running tank. Mix RO water with a Sulawesi mineral salt that buffers to the target, test the finished…
Not daily. In an established tank, Sulawesi shrimp (Caridina spp.) spend the whole day grazing the biofilm and algae already growing on rock, glass and substrate. Prepared food is a top-up on that. The honest interval is the one your…
Less than most keepers expect, and less often than the label on a shrimp food suggests. No feeding ration has been measured and published for Sulawesi shrimp (Caridina spp. from the Sulawesi lake systems), so there’s no gram figure to…
Maturing a Sulawesi tank means two things happening in order. First, a biological filter that clears ammonia and nitrite to zero in warm alkaline water. Then a grazing layer of biofilm and algae grown on the hardscape afterwards. Mix the…
Stabilizing a Sulawesi tank isn’t about hitting a perfect number. It’s about choosing one workable point inside the group’s warm, alkaline range and then removing every process that quietly moves the water away from it. In practice that means four…
If a Sulawesi tank is reading above the typical pH range of 7.5-8.5, the answer isn’t an acid. This is a system built on carbonate hardness. Anything that drags the reading down by adding acid takes the buffer down with…
A Sulawesi tank stays stable because of what you don’t change. The water sits in a warm, alkaline band that holds less oxygen and is less forgiving of waste than a Neocaridina tank, so the routine that keeps a colony…
You raise KH in a Sulawesi tank by preparing new water outside the aquarium with a Sulawesi mineral salt that carries carbonate. Then you exchange that water in over several changes until the tank sits inside the range of 3-6…
