1) Bristle Worms: They vary in length from 1–12 inches and they come in colors ranging from red to orange to brown. They can be detected by their bristles that are hairy and protrude from each segment on both sides of the body. The easiest way of locating them is to wait till it is dark and then take a flashlight and search your tank. Though there is still a bit of debate whether these worms do cause a problem or not, it has been agreed that these worms do cause a problem when they become large and it is then that they start to attack coral, other kinds of invertebrates and fish too.

The solution: The best way to get rid of them is by trapping them by using one of the various commercial traps that can be obtained in the market. Keep in mind that the bristles give a very powerful sting and also, the larger worms can bite. So make sure that you use strong gloves or a pair of tongs when you are removing them.

 

2) Mantis Shrimp: These look like a mix between a lobster and a shrimp. They vary in size from 2 – 12 inches. They are extremely elusive to find in a home aquarium. An indication that these are present is when you hear a loud clicking sound in your aquarium and you also notice that your fish are disappearing. Fact is that they will kill almost all the life forms in your tank.

The Solution: Use a commercial or DIY your own trap to catch them but be careful as these shrimp are extremely aggressive.

3) Montipora-Eating Nudibranchs ; 

These are probably the number one Worst pest that a Saltwater Aquarium can have. It is usually found in SPS corals i.e; Montipora coral as they reproduce tiny versions of adults that can immediately begin eating the coral, can hide in the smallest crevices, and are amazingly resilient to almost all treatments (including starvation!)  Currently, the best treatment is a potassium permanganate (a rather harmful chemical, so use caution) dip in conjunction with a separate treatment tank.

4) Acropora-Eating Flatworms (Amakusaplana acroporae)

Acropora-eating flatworms are really nasty pests for aquariums with Acropora corals as they quickly reproduce, have excellent camouflage by using the coral’s own zooxanthallae, and no in-tank treatment method is yet proven 100% effective without significant losses.  The most common treatment methods are control through weekly removal through blasting them with a turkey baster, and letting the fishes like wrasse ect to eat them up or taking out the coral for a dip .

5) Nuisance Anemones

These are the anemones which reefer dislike. Aiptasia and Majanos are able to clone themselves and overtake an aquarium very quickly.  Their powerful nematocysts (stinging cells) on their tentacles injure nearby corals and deter growth.  Control and eradication is done through natural predation (Berghia nudibranchs, butterflyfish, & peppermint shrimp) or chemical treatments (such as commercially available treatments like Joe’s Juice, kalkawasser paste, or even sodium hydroxide – also very harmful).

6) Xanthid Crabs (Black-Tipped Claws)

Xanthid crabs have black-tipped claws and are often quite hairy (commonly referred to as Gorilla Crabs).  These are common hitchhikers on live rock, but rarely, if ever, reproduce in aquariums.  They are quite destructive to corals, other invertebrates, and sometimes even fish.  They are also difficult to catch since they often hide deep inside rocks and only come out at night.

7) Zoanthid-Eating Spiders

Unfortunately, even saltwater aquariums are subject to getting spiders.  Although these may cause nightmares, they are relatively easy to treat with manual removal (tweezers).  If the zoanthid colony can be removed from the aquarium, it can be treated with a good coral dip to help dislodge the spiders.
