You unbox your new aquarium plants, plant them carefully, and a week later leaves are turning transparent, mushy or falling off. It is one of the most common worries for anyone buying plants online in India. The good news: in most cases this is normal adjustment, not a dying plant. Here is what causes it, which plants are affected most, and how to help them recover.
Quick answer: New aquarium plants often melt in the first 1–4 weeks because they are adjusting to different water, light and temperature, and many were grown out of water (emersed) at the nursery. Remove mushy leaves, keep the roots or rhizome in place, keep conditions stable, avoid moving the plant, and wait. As long as the rhizome, crown or stem base is firm, new leaves adapted to your tank will grow back.
Why do new aquarium plants melt?
- Emersed-to-submerged change: many nurseries grow plants with leaves in the air, which is faster and healthier. Those leaves cannot work underwater, so the plant drops them and grows new submerged leaves.
- Different water chemistry: a sudden change in pH, hardness or temperature from the nursery to your tank stresses the plant.
- Light change: moving from bright nursery light to a basic home LED, or the reverse.
- Transit stress: a few days in the dark during shipping uses up stored energy.
- Planting mistakes: burying the rhizome of Anubias, Java fern or Bucephalandra, or planting stem bundles too tightly.
Which plants melt most after shipping?
| Plant group | Melt risk | What to expect |
|---|---|---|
| Cryptocoryne | High | Often loses most leaves (“crypt melt”), then regrows in 2–4 weeks |
| Bucephalandra | Medium | May drop a few leaves; recovers slowly |
| Carpeting plants (Monte Carlo, Hairgrass) | Medium | Some portions melt or float up if not planted deep |
| Stem plants (Rotala, Ludwigia, Cabomba) | Medium | Lower leaves drop; tops keep growing |
| Vallisneria | Medium | Older leaves melt, runners follow |
| Anubias | Low | Usually just pauses growth; melts only if the rhizome is buried |
| Java fern | Low | Occasional brown leaves; new plantlets appear |
| Floating plants | Low | Recover fast if leaves stay dry |
How to tell melting from a dead plant
Check the base, not the leaves. Leaves are disposable; the growing point is what matters.
- Healthy: the rhizome (Anubias, Java fern, Buce), crown (Crypts, Vallisneria) or stem base is firm and green or white, and roots look pale and intact.
- Dead or rotting: the rhizome or crown is soft, brown or black, smells bad, and falls apart when touched.
If only part of an Anubias rhizome is soft, cut it off with clean scissors and re-attach the firm section. See why Anubias melts or turns yellow.
Step-by-step: helping new plants recover
- Unpack immediately and float plants in dechlorinated water for a few minutes before planting.
- Plant correctly: attach epiphytes to hardscape, plant Crypts with the crown above the substrate, and space stems 2–3 cm apart.
- Remove mushy leaves every few days so they do not pollute the water.
- Keep conditions stable: avoid big water changes, temperature swings or moving plants for 2–3 weeks.
- Keep light moderate (6–8 hours) while plants adjust; strong light on weak plants invites algae.
- Feed gently: add a root tab near Crypts and swords, and a light liquid fertiliser after the first week.
- Be patient: most plants show new growth within 2–4 weeks; slow growers like Anubias and Buce can take longer.
Melting in Indian conditions
- Summer: parcels can get hot in transit; float plants in cool (not cold) dechlorinated water and plant them in a shaded tank.
- Winter in North India: plants arriving from warm nurseries into tanks below 20 °C slow down sharply; use a heater for tropical plants.
- Hard tap water: most plants adapt, but soft-water plants may drop leaves while adjusting.

Frequently asked questions
How long does plant melt last?
Usually 1–3 weeks. Cryptocoryne can take up to 4 weeks to show strong new growth.
Should I remove a melting plant from the tank?
No. Remove only the dead leaves. Pulling or moving the plant restarts the adjustment and slows recovery.
Is plant melting covered by a live-arrival guarantee?
Live-arrival guarantees cover plants that arrive dead. Leaves melting days later while the plant adjusts is normal and not a sign of a dead plant. Anubias.in asks for a clear photo within 24 hours of delivery if a plant arrives dead; see our shipping and live-arrival policy.
Which plants should beginners buy to avoid melting?
Anubias, Java fern, Java moss and floating plants rarely melt after shipping. Start with our best beginner plants.
