Myriophyllum Tuberculatum
Myriophyllum tuberculatum
Also known as Red Foxtail, Tuberculatum Milfoil
Plantae›Tracheophyta›Magnoliopsida›Saxifragales›Haloragaceae
📍 South and Southeast Asia
Red Foxtail is one of the deepest red aquatic plants available. It produces whorls of fine, needle-like leaves that range from orange-red to blood-red under intense light. The feathery texture combined with vivid colouration makes it a showpiece background plant in high-tech scapes. Demanding of light, CO2, and micronutrients.

Tanks keeping this 🌿

Compatible Livestock
Peaceful algae grazers that won't damage plant tissue and help maintain tank cleanliness
Small, non-destructive shrimp that complement planted tanks and add visual interest
Small, peaceful schooling fish that won't uproot or damage delicate plant structures
Algae-eating fish that graze on plant surfaces without causing damage
Complementary stem plant with similar care requirements; creates layered background effect
Foreground plant that pairs well in Nature-style layouts; requires similar nutrient-rich substrate
Common Diseases
Nutrient Deficiency
Yellowing leaves, stunted growth, pale coloration, loss of red pigmentation despite adequate lighting
Increase fertilizer dosing frequency to 3-4 times weekly; verify CO2 levels are 20-30 ppm; test water parameters and adjust macronutrient ratios; consider all-in-one fertilizers designed for planted tanks
Algae Overgrowth
Green or brown algae coating plant leaves, reduced light penetration, plant growth slowdown
Reduce photoperiod to 8-10 hours daily; increase water change frequency to 50% weekly; add algae-eating fish or shrimp; ensure CO2 and nutrient balance to outcompete algae
Melting
Leaves becoming transparent, mushy stems, rapid tissue breakdown after planting
Ensure stable water parameters (pH 5.5-7.0, temperature 22-28°C); increase CO2 gradually over 1-2 weeks; boost fertilization; perform 25% water changes twice weekly until recovery
Slow Growth
Minimal new leaf development, weak stems, plant appearing stalled despite good conditions
Verify lighting is truly high (8-10 hours daily with 2+ watts per liter); confirm CO2 injection is active; increase fertilizer dosing; check that substrate is nutrient-rich; ensure water temperature is 24-28°C
