Summary
- Keep Tiger shrimp cool, clean and stable, often in soft to moderately soft water with not too much KH. OEBT and Red Tiger can differ by breeding line, so always ask the breeder values.
- This advice is meant for readers landing directly from Google who need a complete answer without opening the cluster guide first. It fits normal home aquariums, small breeding setups and species tanks where you use liquid tests, a thermometer and a repeatable maintenance routine. It applies less to acute deaths; then oxygen, ammonia, nitrite, temperature and possible poisoning must be checked first.
- For many Caridina lines, the water source is the system. Use RO water, minerals and active soil only when you understand GH, KH, pH and TDS. Ammonia and nitrite must be zero, oxygen high, temperature cool and stable, and copper or broad medication is especially risky. Low KH also means pH can shift quickly.
- Classic mistakes are keeping Caridina in hard tap water, combining active soil with calcareous rocks, overfeeding soft acidic tanks, using immature aquariums and buying expensive lines before the basics are stable.
Direct answer
Keeping Tiger shrimp. Keep Tiger shrimp cool, clean and stable, often in soft to moderately soft water with not too much KH. OEBT and Red Tiger can differ by breeding line, so always ask the breeder values.
Do not treat the answer as a loose trick. Treat it as a decision about water, shrimp group, tank age and goal. First decide whether you want a display tank, breeding tank, selected color line, algae team or community aquarium. Then decide whether the water you can keep stable fits the shrimp you want to buy. A shrimp that is easy on paper can still start poorly when transport water, shop water and your aquarium differ strongly.

For many Caridina lines, the water source is the system. Use RO water, minerals and active soil only when you understand GH, KH, pH and TDS. Ammonia and nitrite must be zero, oxygen high, temperature cool and stable, and copper or broad medication is especially risky. Low KH also means pH can shift quickly.
Practical decision route
Use this route before buying or changing the tank. Measure first, choose second and adjust last. Do not change water, substrate, filter, food and stocking at the same time, because you will not know which step helped or caused harm.
- Measure pH, GH, KH, TDS and temperature in tank water and new water.
- Ask the breeder or shop for the values in which the shrimp were kept.
- Check that ammonia and nitrite are zero and that the tank already has biofilm.
- Choose the shrimp group that fits your water source and maintenance routine.
- Plan small matched water changes instead of large corrections inside the tank.
- Feed lightly during the first weeks and judge behavior: grazing, hiding, moulting and shrimplet survival.
- Use the sources below to verify sensitive claims about breeding, copper, salt or water chemistry.

Species-group nuance
Neocaridina is usually the most forgiving choice in stable medium-hard tap water, but it still needs minerals, oxygen and a mature filter. Caridina lines such as Crystal Red, Taiwan Bee, Pinto, Boa and many Tiger shrimp often need RO water, GH+ minerals, low KH and sometimes active soil. Sulawesi shrimp are a separate warm alkaline system; do not treat them as ordinary Caridina. Filter shrimp such as Bamboo and Vampire shrimp mainly need mature tanks, current, oxygen and fine suspended food. Amano shrimp are tougher grazers, but their larvae do not grow in ordinary freshwater.

Common mistakes
Classic mistakes are keeping Caridina in hard tap water, combining active soil with calcareous rocks, overfeeding soft acidic tanks, using immature aquariums and buying expensive lines before the basics are stable.
Most mistakes come from putting color or price above the system. Other recurring errors are trusting an immature filter, moving shrimp quickly from very different values, dosing minerals by guesswork, mixing color lines while expecting pure offspring, and adding fish when shrimplet survival is the real goal.
