Coral Rx
Top PickCoral Rx is a coral dip used before adding new frags to help remove hitchhikers like flatworms, red bugs, and some nudibranchs. It is best used as a preventative quarantine tool rather than a full-tank treatment.
Pros
- +Excellent for preventing pests from entering the display tank
- +Simple dipping process for new coral frags and colonies
- +Effective against a broad range of common coral hitchhikers
Cons
- -Does not kill eggs, so repeat inspection is still needed
- -Cannot solve an established pest outbreak inside the display tank by itself
Aiptasia-X
Aiptasia-X is one of the most common spot treatments for eliminating Aiptasia anemones in reef tanks. It is easy to use with a syringe applicator and works well for small to moderate infestations when applied carefully.
Pros
- +Directly targets visible Aiptasia without dosing the whole tank
- +Widely available and simple for new hobbyists to apply
- +Works quickly when the anemone fully ingests the paste
Cons
- -Can cause Aiptasia to spread if the treatment is rushed or incomplete
- -Does not help with flatworms, red bugs, or nudibranchs
Salifert Flatworm eXit
Flatworm eXit is a widely used treatment for red planaria and similar flatworms in reef aquariums. It can be very effective, but beginners need to prepare for toxin release from dying flatworms by siphoning first and using fresh carbon.
Pros
- +Specifically designed for flatworm outbreaks in reef systems
- +Acts quickly when used according to instructions
- +Commonly used by hobbyists and easy to source
Cons
- -Mass die-off of flatworms can foul the tank if not managed carefully
- -Not a solution for red bugs or montipora-eating nudibranchs
Berghia Nudibranchs
Berghia nudibranchs are a biological control option that feed specifically on Aiptasia. They are highly effective over time, especially in tanks where chemical spot treatments have not fully solved the problem.
Pros
- +Consumes Aiptasia naturally and can reach hidden areas in rockwork
- +Reef safe for corals and fish when not preyed upon
- +Useful for persistent infestations that keep returning
Cons
- -Works slowly and may take weeks to months to show major results
- -Can be eaten by wrasses, peppermint shrimp, and other tank inhabitants
Bayer Advanced Complete Insect Killer dip
The Bayer coral dip method is a popular hobbyist approach for knocking off pests like red bugs, flatworms, and nudibranchs from coral frags before they enter the tank. It is highly effective, but it requires careful handling, strict rinse steps, and is not a commercial aquarium product.
Pros
- +Very effective dip for many common coral pests
- +Low cost per dip compared to many specialty products
- +Often used for SPS frags where pest prevention is critical
Cons
- -Requires careful handling because it is not intended for aquarium use
- -Not suitable for in-tank treatment and can be intimidating for beginners
Peppermint Shrimp
True peppermint shrimp, especially Lysmata wurdemanni, are a popular and affordable biological option for smaller Aiptasia problems. They can be effective in nano reefs and mixed reefs, but results vary depending on the individual shrimp and species purchased.
Pros
- +Low-cost natural option for beginner reef tanks
- +May help with small Aiptasia before the infestation becomes severe
- +Adds scavenging behavior and utility to the cleanup crew
Cons
- -Many stores sell look-alike shrimp that do not eat Aiptasia
- -Some individuals may ignore Aiptasia or pick at certain corals and polyps
The Verdict
For most beginner reefers, Coral Rx is the best all-around prevention choice because it helps stop many pests before they reach the display tank. If you already have Aiptasia, Aiptasia-X is the easiest direct treatment for small outbreaks, while Berghia nudibranchs are better for stubborn infestations. For flatworms, Salifert Flatworm eXit is the strongest targeted option, but it demands careful prep and follow-up.
Pro Tips
- *Identify the exact pest before buying a treatment, because Aiptasia, flatworms, red bugs, and nudibranchs all need different approaches
- *Use coral dips on every new frag and inspect for eggs under plugs, branches, and encrusted bases before placing corals in the display
- *Keep fresh activated carbon, mixed saltwater, and a siphon ready before treating flatworms, since die-off can quickly affect water quality
- *Choose biological controls like Berghia nudibranchs or peppermint shrimp only after checking whether your fish or invertebrates may eat them
- *Start with the least disruptive option for your tank, and avoid stacking multiple treatments at once unless you are certain they are compatible
