Two Little Fishies AquaStik Coralline Red Epoxy Putty 4-oz
AquaStik Underwater Epoxy Putty in Coralline Red is a reef-safe adhesive designed for marine and reef aquariums. Originally produced by Two Little Fishies, this epoxy putty blends well with coralline algae and live rock, making it less conspicuous in aquascapes. It is easy to mix and cures reliably in dry, damp, or underwater environments. Because of its quick setting nature, only small amounts should be mixed at a time, and many reef keepers prefer to use the minimal quantity since over time corals tend to grow over the adhesive surface.
AquaStik is frequently used for coral fragging, aquascaping, and securing stony corals, gorgonians, or aquatic plants. It bonds not only to plastic and glass but also to live rock and coral substrates.

Alan Wright –
I used this putty to attach a new coral fragment to my live rock. It set quickly and didn’t show up after a few weeks. The color matches the reef well and it’s easy to work with. Great for fragging without disturbing the environment.
Victor Davies –
Works well for securing gorgonians. I mixed just a small amount and it bonded firmly. The coral didn’t grow over it as expected, which is a plus. Slightly messy when mixing, but overall reliable.

Perfect for aquascaping. The red color blends seamlessly with my coralline algae. It cures fast and stays stable even in damp conditions. I’ve used it multiple times and it’s become a go-to for reef setups.
