Suitable Plants
5Duckweed
The smallest flowering plant — a tiny floating fern that doubles its coverage in days. Excellent nutrient absorber but extremely difficult to remove once established. Use with caution.
Frogbit
A popular floating plant with round, lily-pad-like leaves and long, trailing roots. Excellent for nutrient吸收 and providing cover for fish fry and shy species.
Dwarf Hairgrass
Care profile for Dwarf Hairgrass: medium-high light, medium CO₂, intermediate difficulty.
Salvinia
A small floating fern with distinctive cup-shaped leaves. Fast-growing and excellent for nutrient吸收 in shrimp tanks. Does not reproduce as aggressively as duckweed.
Water Wisteria
Care profile for Water Wisteria: medium light, low CO₂, beginner difficulty.
Compatible Invertebrates
4Nerite Snail
The best algae-eating snail for aquariums. Cannot reproduce in freshwater, so populations stay stable. Comes in zebra, tiger, and olive patterns. Will lay white eggs on glass.
King Kong Shrimp
A solid black color morph of Caridina cantonensis with minimal white markings. One of the rarest and most expensive shrimp variants. Requires expert-level water parameters.
Sulawesi Cardinal Shrimp
A stunning red and white striped shrimp from the ancient lakes of Sulawesi, Indonesia. Unlike most Caridina, it thrives in warm, alkaline water (pH 7.5-8.5, 26-30°C).
Crystal Red Shrimp
A high-grade bee shrimp bred for its striking white-and-red pattern. Demanding keeper: thrives only in soft, acidic water (GH 4-6 dGH) and practically requires reverse-osmosis water with an active buffering substrate. Stable cool temperatures around 22 C are essential.

Common Problems
5F
Fish Hiding or Chronic Stress
Fish hide constantly, refuse food and fade in color.
fishL
Low Filter Flow
The filter output weakens, reducing circulation and filtration.
equipmentH
High Ammonia Poisoning
Elevated ammonia levels cause burns, redness and rapid breathing.
waterT
Temperature Shock
Sudden temperature swings after water changes, heater failure or power cuts stress fish.
fishD
Dropsy
Abdomen swells and scales stand out like a pinecone — usually a bacterial infection.
