✅ Safe Generally considered safe for this species in normal amounts.

Natural driftwood is generally safe for fish. It provides structural enrichment and releases tannins that can lower pH and mimic natural water conditions. Ensure it is clean and free of artificial dyes or preservatives before adding it to the tank.

✅ Emergency: No.

💡 Why

Driftwood releases tannins, which are natural polyphenols that stain water brown and have mild antibacterial properties. These compounds are not toxic to most freshwater fish and can actually benefit certain species like bettas or cichlids. The primary risk is physical injury if the wood has sharp splinters or if it is treated with harmful chemicals.

Important: this is for reference only and is not veterinary advice. If your fish may have eaten or touched something dangerous, contact your veterinarian immediately.

❓ Common questions

Will driftwood stain my water brown?

Yes, tannins leach out of the wood and turn the water tea-colored. This is normal and harmless, though activated carbon can filter it out if you prefer clear water.

Do I need to boil driftwood before use?

Boiling is not strictly necessary but helps remove debris and speeds up the initial tannin release. Soaking it in tank water for a few days is a gentler alternative.

Can fish eat driftwood?

Some species, like plecos or otocinclus, may nibble on soft parts of the wood. It is not a primary food source but can provide minor fiber and grazing opportunities.
