Sea Star-Eating Nano Shrimps



One of my favorite aquariums is my 10 gallon nano reef aquarium. It contains only corals, crustaceans, and other invertebrates, so it's easier to keep clean. Some of the most interesting crustaceans in this tank are the sea star-eating shrimps: Harlequin shrimp Hymenocera elegans and Bumblebee shrimp Gnathophyllum americanum.

Bumblebee shrimp are a perfect livestock choice for a nano reef. They don't eat corals, are safe for fish, and grow less than an inch long. When it comes to feeding, they are not as picky as Harlequin shrimp or Bongo shrimp. They are carnivores who love to eat the tube feet of echinoderms like sea stars and urchins, but will also eat some small bits of frozen mysis or Cyclop-Eeze. If you provide enough sea stars, they will easily survive the attentions of a pair of Bumblebee shrimp. It's also a good idea to stock your nano with some Stomatella snails, as the Bumblebee shrimp snip pieces from the Stomatellas to eat without killing the snail. My Bumblebee shrimp is often seen harassing one of my many quickly-reproducing Stomatella snails.

Harlequin shrimp make are a great "showy" creature for a nano reef. Their beauty is surpassed by few other crustaceans. Harlequin shrimp are large enough that they are easy to spot, but small enough (only a couple inches) that they can be kept in a nano aquarium. They can be kept singly, but it's much more interesting to keep a pair. They seem to use their giant, paddle-like chelipeds to communicate with one another, perhaps coordinating their sea star attacks.

It is very easy to sex Harlequin shrimp. Females have tiny, color-spotted swimmerettes on the underside of the tail. Males have a clear, colorless underside. Two males or two females should not be housed together, but males and females pair easily and without aggression.

Unlike the Bumblebee shrimp, Harlequin shrimp consume the whole star, not just the feet. They use their large front claws to pinch and pry the legs of sea stars from their substrate, then force the sea star onto its back where it is helpless. They can keep a sea star alive for long periods of time while feasting on them.

Harlequin shrimp only eat sea stars. They don't eat brittle stars, however. The most readily available food sources for Harlequin shrimp are the tiny, hitchhiking Asterina stars, Chocolate Chip or African Knob, Linkia, Fromia, or Sand sifting stars. Linkia and Fromia stars are difficult to keep in captivity and more expensive. Remember, though, that the hardy, inexpensive Chocolate Chip and African Knob stars are not reef safe. It is possible to house a few Chocolate Chip stars separately from your nano aquarium and cut a leg off to feed the Harlequin shrimp, then allow the removed legs to grow back.

Hawaiian Harlequin shrimp are the most colorful, but they command pretty high prices and are more rare. The Indonesian variety is a little less expensive and may be purple, blue, or a combination.

Bongo shrimp are related to Harlequin shrimp, and eat both Sea Stars and Brittle stars. They are much smaller, growing to only an inch. They're also much more rare and command a price between $100 - $130 a pair. Here is a video by Liveaquaria.com of Bongo shrimp eating brittle stars.

Strawberry crabs are considered to be reef safe "with caution." As far as crabs go, this species is one of the more coral safe crabs.

This little crab was found as a hitchhiker at The Hidden Reef in Levittown, PA. It now resides in my 10 gallon nano tank. So far it is not bothering any of the corals or its peaceful crustacean tank mates.

Naxiodes taurus

Sometimes called the Soft coral crab or decorated horn crab. Commensal on soft corals, gorgonians, and sea fans. This one was found in the folds of a Leptoseris at The Hidden Reef in Levittown, PA.

I put this crab in my 10 gallon nano tank. This tank has no fish in it, only corals and small, reef safe crustaceans.

How to Kill Hydroids in Dwarf Seahorse and Fry Tanks


Hydroids are tiny jellyfish-like creatures that infest tanks with low flow, such as seahorse fry tanks and larval rearing vessels. The bad news is, they can sting and kill dwarf seahorses and fish fry that get too close to them. Hydroids love to eat baby brine shrimp and can be introduced to the tank on almost anything, including the shells of brine shrimp eggs.

There are a couple things you can do to prevent contamination of your tank with hydroids. Make sure you are using decapsulated brine shrimp eggs, or decapsulate them yourself. You can buy already decapsulated brine shrimp from seahorsesource.com.

Your best weapon against hydroids is a drug called Fenbendazole (Panacur). However, you should familiarize yourself thoroughly with this drug before using, or better yet, talk to your veterinarian first. Reeftools and its colleagues can not be held responsible for any result of you reading this blog and using Fenbendazole. Personally, I’ve used this drug safely with dwarf seahorses and Fundulus heteroclitus Killifish. I’ve read that it can be safely used with other fish fry such as Clownfish. In low doses it can be safe for clean up crews such as Nassarius snails, cleaner shrimp, and hermit crabs. Be careful and do lots of research before using Fenbendazole.

Any living creatures or plants you want to add to your dwarf seahorse or fry tank should be treated with Fenbendazole first. Keep in mind, most invertebrates and corals DO NOT tolerate Fenbendazole and will die. Macroalgae such as Caulerpa and Chaetomorpha as well as the beneficial nitrifying bacteria in live rock handle treatment with the drug very well. Fenbendazole is by no stretch of the imagination considered to be reef safe. So don’t dose your reef tank with this stuff. Fenbendazole also tends to absorb into glass and rock, leaching into your tank forever. The granules seem to leach worse than the liquid does.

What should you do if you find hydroids in your dwarf seahorse tank or fry tank? Fish seem to tolerate Fenbendazole treatments well. Unfortunately, hydroids don’t even flinch from other common parasite treatments like low salinity, Praziquantel, or formalin baths. So far only Fenbendazole has proven an effective treatment.

Where can you get Fenbendazole? There are plenty of online or local farm animal feed stores that carry it. I use Safe-Guard Fenbendazole/liquid Goat Wormer by Intervet (fenbendazole) Suspension 10% (100 Mg/ml). It’s very important to choose one that is not flavored. Make sure you have done plenty of research and are aware of the risks of using this medication before you proceed. The dosage for fry tanks is 0.2 ml per 10 gallons. Repeat the dosage every other day for a total of three dosages. By the third dose, all hydroids should be dead.

Fenbendazole can also eradicate Aiptasia, bristleworms, and other marine worms.

hybrid guppy endler pintail

This is one of my favorites. He is an old man now; he even moved from Wisconsin to PA with me in January. His father is an albino endler hybrid created by Adrian HD and his mother came from a line of yellow snakeskin doubleswords I'd been breeding for many years.

pistol shrimp long leg

On June 14th my co-worker Bill at The Hidden Reef in Levittown, PA noticed an extraordinarily long, but thin, shrimp leg darting in and out of a series of holes that appeared to be drilled through the top of the rock. He chiseled open the rock and found this pistol shrimp. The pistol shrimp had to have been growing inside the rock unable to leave since it was very young, similar to the way a gall crab grows inside a coral. If anyone recognizes this pistol shrimp and can identify it, please go to http://reeftools.com/news/unusual-pistol-shrimp-hitchhiker/ to leave a comment

Coral Eating Nudibranchs and Slugs

Always check new corals for coral eating nudibranchs and slugs. Many people are familiar with the Zoanthid eating nudibranchs, but there are nudibranchs and slugs that eat all types of corals. These pests are well camouflaged and not easy to spot, preferring to hide at the base of their hosts. Look for them around receding tissue, polyps that won’t open, or dead white skeleton. It is strongly recommended to quarantine new corals and to dip them in a coral dip, flatworm exit, or iodine before placing them in the tank.

Tritonia spp. nudibranchs are often seen on purple Gorgonians from the Caribbean and can do serious damage in a short time if not removed. Unfortunately, they are extremely tiny and transparent. LPS eating slugs like the Turbinaria eating slug and Scolymia eating slug are not particularly common, but they show up from time to time. Removal is not difficult since they are relatively large and don’t seem to reproduce in captivity. Phestilla melanobrachia is a nudibranch that eats Dendrophyllid corals and grows up to 2 inches in length. They are usually found on Tubastrea spp. corals in captivity. Small Zoanthid eating nudibranchs are fairly common on almost types of Zoanthids. There are countless other species of slugs and nudibranchs that eat other corals like Xenia, tree corals, Montipora, etc.

Anatomy of an Aeolid Nudibranch

Zoanthid eating nudibranchs and Tubastrea eating nudibranchs are both types of Aeolid nudibranch. The black specks behind the first two antennae are the eyes. The finger-like appendages on the back are called cerata. The darker tips of the cerata are called cnidosacs. A Zoa eating nudibranch can consume immature nematocysts from its prey and store them in these sacs for protection against predators. The nudibranch also gets its coloration from its prey. Like their cousins the photosynthetic Elysia spp. slugs, Zoanthus eating nudibranchs even steal zooxanthellae from the Zoanthus.
Reefers have had success eradicating the Zoa eating nudibranch with Salifert’s Flatworm Exit in high doses. Obviously, you have to be careful using this method. It’s best to take affected colonies out of the tank and treat them in a bucket of tank water with an overdose of Flatworm Exit. If you have a lot of hidden planaria (which release toxins when they die) in your main tank, it could crash. Have several pounds of carbon on hand when using Flatworm Exit. Since Flatworm Exit won’t kill the eggs of the nudibranch, you need to repeat the treatment four days later. These treatments may work on other types of coral eating nudibranchs and slugs.

 This is a Phestilla melanobrachia, a Dendrophyllid eating Aeolid nudibranch sometimes found on sun corals Tubastrea spp. in captivity.

Commensal Acropora Palaemonid Shrimp


What kind of shrimp is this? I thought maybe a Palaemonid shrimp of the genus Cuapetes or Palaemonella. Not sure. I found it on an Acropora millepora last week and threw it in my frag tank. I brought home this tiny Acro frag last night (from The Hidden Reef in Levittown, PA), and the shrimp has decided to host on it...The shrimp isn't hurting the frag, just really, really likes it. There are plenty of places to hide, including a dead Acro colony, but the shrimp insists it wants an Acro I guess.

The Hidden Reef Revealed

In 2009 I remember reading an article in TFH magazine about a store called The Hidden Reef in Levittown, PA near Philadelphia. I found myself wishing we had more local fish stores like that nearby. A year later my wish was granted when my husband was offered a job in Philadelphia. At the time I was the photographer/identifier for Liveaquaria’s Diver’s Den, and I absolutely loved my job. I was worried I might not be able to find a job that would allow me to stay in the reef industry, but I always had that article about The Hidden Reef in the back of my mind. Everything fell into place, and I am now working for The Hidden Reef! It’s different from what I’m used to, but I’m enjoying the hands-on approach and interacting with customers and my co-workers who are also knowledgeable hobbyists.



Even if you don’t live in the area, it’s definitely worth making a trip to check out the store. Right now we have (in my opinion) the best selection of corals in the area including Acroporas (even a blue one for $59.99!), a fat Copperband Butterfly that eats frozen brine, a Caribbean Red Scorpionfish that eats frozen mysis, a fabulous LED tank with fluorescing corals, a Potter’s Angel, a BREEDING pair of clingfish, my personal favorite Hawaiian Red Leaffish, and countless other fish, corals, inverts, and dry goods. I hope to see you there soon; be sure to say hi!
