Cryptocoryne wendtii is a popular, low-maintenance rosette plant available in several colour forms from green to brown-red. It may undergo 'crypt melt' when first planted or after water chemistry changes, but almost always recovers. Once established it is resilient and spreads via runners.

Tank Mates

Otocinclus

Small, peaceful algae grazers that won't damage plant leaves and thrive in similar water parameters

excellent

Red Cherry Shrimp

Gentle invertebrates that graze algae without harming plants; prefer the same soft, slightly acidic water

excellent

Emerald Dwarf Rasbora

Tiny, peaceful fish that school in open water while the plant provides shelter and shade

good

Dwarf Hairgrass

Complementary foreground plant with similar nutrient requirements and low-light tolerance

excellent

Anubias Nana

Hardy companion plant with identical care needs; both thrive in low to medium light without CO2

excellent

German Blue Ram

Peaceful dwarf cichlid that appreciates planted tanks; may occasionally uproot plants while foraging

good

Common Diseases

Crypt Melt

Symptoms

Rapid leaf yellowing, blackening, and deterioration; leaves dissolve or fall away within days to weeks

Treatment

Maintain stable water parameters (pH, temperature, hardness); avoid drastic changes; ensure adequate lighting and nutrient supplementation; affected leaves will regrow once conditions stabilize

Nutrient Deficiency

Symptoms

Pale or yellowing leaves, stunted growth, weak or translucent new growth, loss of vibrant coloration

Treatment

Add root tabs beneath the substrate; dose liquid fertilizers containing macronutrients (N, P, K) and micronutrients (iron, boron); perform regular water changes to replenish trace minerals

Algae Overgrowth on Leaves

Symptoms

Green, brown, or black algae coating leaf surfaces; reduced light penetration to plant tissue

Treatment

Reduce lighting duration to 8-10 hours daily; increase water circulation; manually remove algae with a soft brush; introduce algae-eating fish like Otocinclus or shrimp; avoid excess nutrients that fuel algae

Root Rot

Symptoms

Mushy, blackened roots; foul odor from substrate; plant fails to anchor or shows severe decline despite adequate light

Treatment

Improve substrate drainage and water circulation; reduce organic debris accumulation; perform partial water changes; consider replanting in fresh substrate with root tabs; ensure temperature remains within 22–28 °C
