This page contains Aiptasia photos to help you identify your invasive anemone. The first step to controlling an Aiptasia infestation is proper identification. It does little good to invest time and money into a solution to the wrong problem.
Cotton candy algae is considered to be a nuisance algae. There are many species of cotton candy algae, none of which you want to see in your reef tank.
Most saltwater hobbyists will deal with pests at some point. Maybe they traded frags with a friend. Maybe they bought imported livestock and failed to quarantine or treat it. Whatever the reason, some reef aquariums with acropora species may become infested with a pest commonly called red bugs. These red bugs feed on smooth skinned Acropora spp. such as A. granulosa, A. tortuosa, A. caroliniana, and A. echinata. Red bugs do not always kill the coral on which they live. But they can affect growth rate and overall health. It is also considered a bad practice to knowingly trade or sell infested corals to other hobbyists without first explaining the issue.

Red Slime Algae AKA Cyno bacteria The common name for cyanobacteria is "red slime" algae. Red slime algae is actually a bacteria and not an algae. Cyanobacteria means blue-green algae and comes from its color yet there are many other colors of cyanobacteria. The one color of cyanobacteria that aquarist are most concerned with is red. Red slime algae can start out in small patches and then combine to cover a large area.
Flatworms are a pest that can be removed from the reef aquarium. There are several types of flatworms in the marine aquarium but they can all be killed or removed the same way. Some say some saltwater fish are known to eat flatworms but I have had no luck with fish getting rid of this pest and this includes trying several types of wrasses.
Many people ask if Berghia nudibranchs will eat majano anemones and what they look like. This article is created to help those people remove this invasive species of anemone from their reef tanks because Berghia only eat Aiptasia. Fortunately majano anemones are much easier to remove than aiptasia. From my experience, the methods that will be described later in this article work well on majanos but is not very effective on aiptasia. This method is also a cheap, easy, and a quick way of removing majanos anemones.
Zoanthids, sometimes called zoas, are popular, hardy corals. They will occasionally suffer from a pest or disease that may be introduced with them or by new tank inhabitants. A few of the more common pests you may encounter include zoanthid eating nudibranchs, sea spiders, and sundial snails. Zoa pox is also a common affliction among zoanthids.
