Creating the Ideal Blue Eye Rainbowfish Home

Tank Size

Most Blue Eye Rainbowfish are ideal for aquariums from 30 litres and above. Larger aquariums allow bigger schools and more natural behaviour.

Temperature

These tropical fish thrive between 22–27°C, with excellent water quality and stable conditions.

Water Quality

Ammonia: 0 ppm
Nitrite: 0 ppm
Nitrate: ideally below 20 ppm
pH: 6.5–7.8

Blue Eye Rainbowfish appreciate mature aquariums with regular water changes and stable parameters.

Filtration

Moderate water movement is appreciated. Sponge filters, hang-on filters or canister filters all work well provided they maintain excellent biological filtration.

Aquascaping

Dense planting around the edges with open swimming space through the centre creates the perfect environment. Floating plants help reduce stress while driftwood and fine-leaved plants encourage natural displaying and breeding behaviour.

Feeding Blue Eye Rainbowfish

These small fish have surprisingly big appetites and enjoy a varied diet.

Premium nano pellets
Quality flakes
Baby brine shrimp
Daphnia
Frozen foods
Microworms and live foods

Feeding a varied diet helps maximise colour, health and breeding activity.

Suitable Tank Mates

Blue Eye Rainbowfish are peaceful and thrive alongside other gentle community fish.

Suitable companions include:

Small Tetras
Rasboras
Corydoras
Otocinclus
Peaceful Gouramis
Shrimp (in well-established planted aquariums)
Other peaceful Rainbowfish species

Avoid large or aggressive fish that may intimidate or prey upon these small species.

Blue Eye Rainbowfish FAQs

How many Blue Eye Rainbowfish should I keep?

They are schooling fish and should ideally be kept in groups of at least six, with eight to ten or more producing the best colour and natural behaviour.

Are Blue Eye Rainbowfish suitable for nano tanks?

Yes. Most species thrive in well-maintained planted aquariums from around 30 litres upwards.

Do Blue Eye Rainbowfish eat shrimp?

Adults generally coexist well with adult shrimp, although very small shrimp or shrimplets may occasionally be eaten.

Are they easy to breed?

Yes. Given excellent water quality, fine-leaved plants or spawning mops and quality food, many species breed readily in the home aquarium.

Why are my Blue Eye Rainbowfish displaying?

Males constantly display their fins and colours to impress females and establish their place within the group. This behaviour is one of the highlights of keeping Pseudomugils.
