Myriophyllum Mattogrossense
Myriophyllum mattogrossense
Plantae›Tracheophyta›Magnoliopsida›Haloragaceae
📍 Mato Grosso, Brazil
Myriophyllum mattogrossense produces feathery red-green whorled leaves on reddish stems, creating an ornate background plant. Under high light and CO2 the foliage intensifies to deep burgundy. It is a fast grower that needs regular trimming.
Tank Mates
Small, peaceful algae grazers that won't damage delicate plant leaves
Gentle invertebrates that graze algae and won't uproot or consume healthy plant tissue
Small, peaceful schooling fish that benefit from dense plant cover for security
Complementary foreground plant that creates layered aquascaping with this background species
Gentle bottom-dweller that won't uproot plants and appreciates the shelter provided
Larger shrimp species that actively controls algae without harming established plant stems
Common Diseases
Nutrient Deficiency (Iron/Macronutrient)
Yellowing of new leaves, stunted growth, pale coloration despite adequate lighting
Increase liquid fertilizer dosing to 2x weekly; ensure CO2 is supplemented at 20-30 ppm; test water parameters and adjust NPK ratios
Algae Overgrowth (Green Water/Hair Algae)
Cloudy water, visible hair algae on stems, reduced plant vigor
Reduce lighting duration to 8-10 hours daily; increase water change frequency to 30-40% weekly; introduce algae-eating fish like Otocinclus or shrimp; ensure CO2 and nutrients are balanced
Stem Rot/Decay
Mushy, darkening stems; leaves detaching easily; foul odor from substrate
Remove affected stems immediately; improve water circulation with increased aeration; reduce organic waste through more frequent water changes; ensure substrate is not compacted
Slow Growth/Melting
Leaves becoming translucent and dissolving; minimal new growth; overall plant decline
Verify lighting is 8-10 hours daily at medium-high intensity; increase CO2 to 20-30 ppm; dose comprehensive liquid fertilizer weekly; check water parameters (pH 6.0-7.5, temperature 22-28°C)
