Seachem Flourish Glue 8g (2 x 4g Tubes)
Plant it once and it stays put. Seachem Flourish Glue is a cyanoacrylate gel made for aquascaping – it bonds moss, anubias, bucephalandra and other epiphytes to rock, driftwood and gravel in seconds, and it sets underwater, so a rescape doesn't mean draining the tank.
Key features
- Bonds within seconds, submerged or dry, with a 20-second press for a strong hold.
- Anchors bunch plants – a dab of glue on the stems before planting keeps them in the substrate instead of floating free.
- Works in freshwater and saltwater aquascapes.
- Doubles as a plastics repair glue for aquarium equipment and accessories.
- Aluminium tubes keep the gel fresh far longer than a plastic bottle between uses.

Common questions
Can I use Flourish Glue underwater?
Yes, it's designed to bond both submerged and out of water, in seconds either way.
Is it safe for fish and shrimp once cured?
Once cured it's inert and used widely for planting mosses and epiphytes in livestock tanks. Uncured, it bonds skin and eyes in seconds – keep it away from children and rinse eye contact with water for 5–10 minutes.
Can I use it on glass?
No – Seachem states it isn't intended for adhering items to glass surfaces.
What's the difference between Flourish Glue and Flourish Epoxy?
Glue is a fast, seconds-set cyanoacrylate for attaching moss and small plants to a surface. Epoxy is a slower, five-minute-working-time putty for structurally bonding rocks and driftwood together – use Glue for planting, Epoxy for hardscape construction.
