Delicate Blue Eyes (Pseudomugil Tenellus) 3cm

Delicate Blue Eyes (Pseudomugil tenellus) – A Graceful Gem for Your AquariumThe Delicate Blue Eyes (Pseudomugil tenellus) is a small, peaceful fish species native to the clear, slow-moving streams and wetlands of Australia and New Guinea. With their bright blue irises, shimmering bodies, and delicate fins, these fish captivate aquarists with their understated beauty. Furthermore, their calm temperament and adaptability make them an excellent choice for nano tanks or as a standout addition to peaceful community aquariums.Size and LifespanThe Delicate Blue Eyes is a petite species, growing to a maximum size of just 4 cm. Despite their small size, they are hardy and can live up to 3–4 years with proper care. To ensure their longevity, provide a stable environment with clean, well-oxygenated water. Additionally, a varied diet will promote their overall health and enhance their vibrant colours.Ideal Tank SetupWhen setting up a tank for Delicate Blue Eyes, it’s important to replicate their natural habitat. A tank as small as 40 litres (10 US gallons) can suffice, although a larger tank is ideal for schools of 6–8 fish. Use a soft, sandy substrate and include live plants like Hornwort, Java Moss, or Dwarf Hairgrass to create a lush environment. Driftwood and leaf litter can also help mimic the subdued tones of their native wetlands.Maintain a water temperature of 22–28°C and a pH level between 6.0 and 7.5. The water flow should be gentle, as these fish prefer calm waters. Adding floating plants will not only reduce light intensity but also provide them with additional comfort and hiding spots.Compatible Tank MatesThe Delicate Blue Eyes is peaceful and thrives in a community setting when paired with other non-aggressive species. Ideal tank mates include small tetras, rasboras, corydoras, and shrimp. However, avoid housing them with larger or boisterous fish, as these can outcompete the delicate species for food or cause stress. Keeping them in a group of their own kind is highly recommended to encourage natural schooling behaviour and social interactions.Feeding and NutritionIn their natural habitat, Delicate Blue Eyes feed on small invertebrates, algae, and biofilm. In captivity, they require a varied diet to maintain their health. Offer them high-quality micro pellets, crushed flakes, and live or frozen foods such as daphnia, brine shrimp, or cyclops.Feed them in small amounts twice daily to prevent overfeeding and water quality issues. Occasionally supplement their diet with finely chopped vegetables or spirulina to mimic their natural diet and boost their immune system.Breeding and BehaviorBreeding Delicate Blue Eyes is relatively straightforward, especially when they are kept in a well-maintained tank. Males, identifiable by their longer fins and brighter colours, will display courtship behaviours to attract females. Once a pair is formed, the female will lay her eggs on fine-leaved plants or spawning mops.After the eggs are laid, it’s best to remove them to a separate tank to prevent predation. The eggs typically hatch within 7–10 days, and the fry can be fed infusoria or powdered fry food. Watching the fry grow into their delicate adult form is a rewarding experience for any aquarist.Species OverviewSpecies Name: Pseudomugil tenellusCommon Name: Delicate Blue EyesOrigin: Australia and New GuineaDiet: Omnivorous (micro pellets, live/frozen foods, algae)pH Range: 6.0–7.5Temperature: 22–28°CCurrent Size: 3 cmMaximum Size: 4 cmTank Size: 40L (10 US gallons) minimumFAQsHow large do Delicate Blue Eyes grow?
