Why plant quarantine matters
New aquatic plants can carry snails, eggs, algae, pests, or residues from another system. Most arrivals are healthy, but separating new plants gives you time to inspect them before they share water with fish, shrimp, and established plants.
Before the plants reach the tank
- Prepare a clean container with dechlorinated water and a light source.
- Keep the plant packaging and purchase date nearby so you can identify the source later.
- Inspect leaves, stems, rhizomes, roots, and attached material under bright light.
- Remove dead or damaged tissue with clean scissors.
Rinse without damaging the plant
Rinse plants gently in temperature-matched dechlorinated water. Avoid scrubbing delicate leaves. Rhizome plants such as Anubias and Java fern should not have their rhizomes buried, while rooted plants should be handled by the roots or lower stem instead of the leaves.
Use a separate observation container
Keep new plants apart from the display aquarium when possible. A simple container with clean water and moderate light is enough for observation. Change the water when it becomes cloudy or fouled, and look for new algae, snails, eggs, or tissue damage over the next several days.
Acclimate to the aquarium’s conditions
Once the plant looks clean and stable, move it gradually into the aquarium. Match temperature, avoid pouring unknown shipping water into the display, and plant according to the species’ growth habit.
- Anubias, Java fern, and Bucephalandra: attach the rhizome to rock or wood.
- Cryptocoryne and swords: plant the roots while keeping the crown clear.
- Stem plants: separate bunches and plant individual stems with space between them.
- Mosses: attach thinly so light and flow can reach the growing surface.
Expect some transition
Plants grown above water may lose older leaves after submersion. This is often called melt. Remove decaying leaves, keep the light schedule steady, and wait for new submerged growth before changing several variables at once.
San Diego and Southern California note
Room temperature, source water, and shipping conditions can vary widely across San Diego, Orange County, Los Angeles, the Inland Empire, and Baja California. Match temperature carefully and test your aquarium if a new plant arrives alongside livestock or a major water change.
