The Strawberry Rasbora (Boraras naevus) is a stunning nano fish known for its tiny size, peaceful nature, and vibrant strawberry-pink hues. At just 1.2–1.5cm, this species is among the smallest aquarium fish available, yet it makes a big impact with its color and activity. Native to the soft, tannin-rich waters of southern Thailand, the Strawberry Rasbora thrives in well-maintained, heavily planted aquariums and shows best behavior when kept in groups. Its subtle body markings, including a distinctive dark central spot, add charm to its glowing pink body.

This rasbora is ideal for nano tanks, shrimp-safe setups, and aquascaped displays where gentle water flow and soft lighting allow its colors to shine.

🌊 Water Conditions

Strawberry Rasboras do best in soft, warm, stable water with plenty of plant cover:

Floating plants, leaf litter, and shaded areas help mimic their natural environment and reduce stress.

🐟 Tank Mates

Due to their tiny size and gentle disposition, Strawberry Rasboras do best with similarly peaceful nano fish or in species-only tanks.

Compatible tank mates include:

• Chili Rasboras

• Ember Tetras

• Dwarf shrimp (e.g., Cherry or Amano shrimp)

• Otocinclus

• Pygmy Corydoras

• Snails (e.g., Nerite or Mystery Snails)

Avoid:

• Larger or fast-swimming fish

• Aggressive or boisterous species

• Any fish that may view them as food

Always keep them in schools of 8 or more to reduce shyness and encourage natural behavior.

🍽️ Feeding Habits

Strawberry Rasboras are micro-predators and thrive on small-sized foods.

Ideal diet includes:

• High-quality micro pellets

• Crushed flakes

• Live or frozen baby brine shrimp, daphnia, microworms

• Freeze-dried cyclops or tubifex (crushed)

Feed 1–2 times daily, offering only tiny portions they can eat in under 2 minutes.

🧼 Care and Maintenance

• Perform small, regular water changes (15–25% weekly)

• Ensure stable parameters; sudden changes can cause stress

• Use a sponge filter or low-flow system to prevent strong currents

• Monitor tankmates closely to prevent competition or bullying

• Maintain good water quality and avoid overcrowding

These fish may be small, but they are sensitive and appreciate a clean, calm, and well-planted tank.
