Keeping the Fire Shrimp: Lysmata debelius

The Blood Red Fire Shrimp is one of the most sought-after invertebrates in the saltwater aquarium hobby–because of the amazing color, delicate gracefulness, and fascinating cleaning behavior. Don’t take my word for it, take a look at this beautiful creature. Have you ever seen such a deep red color in the natural world?

Quick facts

Common names: Fire Shrimp or Blood Red Fire Shrimp 

Scientific name: Lysmata debelius

Care level: Easy

Aggression: Low – compatible with a lot of other peaceful reef aquarium inhabitants

Typical adult size: 2 inches (~50 mm)

Minimum tank size: 

Is it a cleaner?: Yes, the Blood Red Fire Shrimp is considered a cleaner shrimp

Diet: Carnivorous diet, eats meaty foods, will clean up uneaten food around the tank and capture floating food

Reef safe: Yes, this animal will very likely leave your corals and other invertebrates alone. It will also get along with peaceful saltwater fish that will leave it alone (or allow the shrimp to clean them)

Most active: Nighttime is when this cleaner shrimp will be most active. During the day, you may find them on the underside of a live rock ledge, or behind it

Ideal habitat

A Blood Red Fire Shrimp will be at home in small and large tanks alike–they are perfectly suitable in a nano aquarium or large reef setup. Fire Shrimp are sensitive to nitrites and ammonia in water, so the tank should be fully cycled before introducing them and you will want to have some experience managing a saltwater tank and keeping nitrate levels down. Copper should be avoided at all costs, so remove the shrimps if any of your fish need to be treated with copper-based medicine. Copper is used to kill parasitic invertebrates, like saltwater ich, but it will also kill your shrimp. So don’t do it.

Fire Shrimp can be a bit shy and sensitive to bright light, at times, and would benefit from having some live rock structure to retreat to for safety.

The fire shrimp is considered a cleaner shrimp

The Blood Red Fire Shrimp is also considered to be a cleaner shrimp species, along with the Scarlet Skunk, Coral Banded, and Peppermint shrimps. It should set up a ‘cleaning station’ in your tank–a part of the shrimp’s territory where fish will swim up and receive a complimentary cleaning service–which means the shrimp will pick off dead scales, skin and remove parasites from the fish. Watching this behavior, in action, is one of my absolute favorite things in this entire hobby.

Check them out in action in this video below!

Feeding and diet

The Fire Shrimp doesn’t have any particular nutritional or feeding requirements that are noteworthy, per se. As mentioned earlier, they are a cleaner shrimp species and will eat parasites and dead skin off your fish. They will also scavenge and eat leftover food, including thawed frozen foods, flakes, and pellets in the tank. I’ve also heard of shrimp eating the food right out of the hand of an aquarist. If you have an ultra-clean SPS tank (low bioload, low feedings), you may want to target feed your shrimp–but otherwise, they are likely to be alright as long as your tank is sufficiently fed. You will want to monitor to make sure they are eating well and aren’t always bullied out of eating.


Blood Red Fire Shrimp are absolutely incompatible with hawkfish or marine bettas. I would approach adding them to any tank with a fish large enough to eat them because I have even had a relatively large flame cardinal fish swallow a cleaner shrimp whole within seconds of adding the shrimp to the tank.

Fire shrimp may also pick at some of your prized corals, so be warned, if you intend to add them to your reef tank.

Behavior and tank mates

The fire shrimp is primarily a shy, nocturnal creature, which means you probably won’t see a whole lot of them in your tank. Which is a bummer, considering how beautiful (and expensive) they are. Over time, and with some strategically timed feedings, you may be able to coax them out of hiding more frequently. ‘s you won’t see them around during strong light times. Instead, they will go out looking for food when light is off, or during dim light periods. If their other tank mates or live plants don’t actually require very strong lighting, you can provide only a small amount, so you can enjoy your cleaner shrimp more.

With the gigantic exception for the fish that will prey on and eat the Fire Shrimp, it is otherwise compatible with most other community reef fish and is probably advantageous if you are keeping fish that are notoriously susceptible to parasites, like the blue hippo tang.

Like most of the animals we keep in the saltwater aquarium hobby, there can be aggression between blood red fire shrimp or even other cleaner shrimp, like the skunk cleaner shrimp. A little shrimp-on-shrimp aggression can be expected, so it is probably best to keep one per tank.

Fire shrimp are also pretty smart and may learn to recognize you (at least as a food source). There are reports by some aquarists that their scarlet cleaner shrimp ‘greets’ them when they approach the tank or climbs onto their hand or takes food from their hand.

The shrimp I have kept, over the years, have been afraid of me, more than drawn to me, but this sounds like a pretty cool reason for me to try them again.

The Fire Shrimp has been bred in captivity. They are hermaphrodites, meaning they have both male and female reproductive organs, which means you are guaranteed to have the genetic materials needed for reproduction with any pair of shrimp. Now that doesn’t guarantee that the two individuals you get will be compatible, but it sure does suggest pairing up shouldn’t be too hard. Contrast this with saltwater fish, where you might need to buy as many as 5-7 specimens to all but guarantee a male/female connection.

Breeding any saltwater fish or invertebrates is a somewhat advanced topic. If you want to learn more about breeding cleaner shrimp, I recommend you check out two sources. The first source is a website called MOFIB. There are some helpful forum threads with important information about breeding this shrimp.

The second resource I recommend you check out is a book that I have on my own personal bookshelf, How to Raise & Train Your Peppermint Shrimp (affiliate link). Ok, so the book is written about a different species of shrimp, but many of the lessons can be applied broadly.

Pros and cons of keeping the  Blood Red Fire Shrimp, Lysmata debelius

Like with any tank inhabitant, these shrimps also have their pros and cons when keeping them.


  • They can remove harmful parasites and dead skin from your fish
  • Will help keep the tank clean by eating leftover food
  • They are relatively easy to keep and don’t require any special diets or water parameters

  • May nibble at corals in reef tanks, especially during the night, when you can’t see them
  • They will spend a lot of time hidden in their cave, so you may not see them around very much–the blood red fire shrimp I have in my tank only comes out in the dark and when it is feeding time

Fire shrimp vs. Cleaner shrimp (Scarlet Skunk)

So, if you are looking to buy a cleaner shrimp species, how should you decide whether to go with the Fire shrimp vs. Cleaner shrimp (Skunk)?

Fire shrimp vs. skunk cleaner shrimp: choose one or booth?

Here are a few things to consider:

Appearance: It’s hard to argue that both species aren’t gorgeous, but which do you think is the most beautiful? That’s going to be a personal choice. Personally, I’d take the Fire shrimp.

Price: Lysmata debelius is almost always more expensive than Lysmata amboinensis. Depending on your budget, that factor could sway you in either direction. If money is no object, then the Fire shrimp may be a bit more exclusive. If you are looking for a great shrimp at a more reasonable price, the Skunk cleaner is your arthropod of choice.

Active cleaning: How important for you is it to observe the active cleaning behavior? Based on my personal experience, the skunky cleaner shrimp with cleaner in the name gets an antenna ahead of that race.

The good news is that the two species are compatible with each other, so perhaps we don’t have to think about it as either or–why not go for both?

    We have had our Fire Shrimp (Jacques) for about 2 years. He had a mate when we first purchased him but months later, the other passed. Jacques has molted a few times and only hides immediately after molting for a few hours. Perhaps we just got lucky – ours is out and incredibly high profile all day and night long! We just upgraded from a 56-gallon cube to a 75-gallon bow front. We are now seeing constant cleaning-station behavior with Jacques and our Raccoon Butterfly and our newly acquired, rather large, Foxface Rabbitfish! Jacques completely stands on these two fish to clean them, walking all over them and they tolerate it very well! It’s hilarious to watch!

    1. Jess, thanks for sharing your experiences with keeping fire shrimp! I’m quite jealous that yours is out in front all the time. Also cool to see the cleaning behavior. Thank you very much for sharing.

      I have a cskunk shrimp and a fire shrimp living together in a 180 litre tank, the skunk shrimp we see all the time but the fire shrimp does come out especially at feeding time, the fire shrimp is more dominate than the skunk shrimp but they stay out of eachothers area, i wouldnt have a tank without them

      1. Hi Steven, thanks for sharing your experiences with both of these cleaner shrimp. They are amazing creatures. So fun to watch.

    Hi, I enjoyed your article.

    Our fire shrimp is actually very sociable, out and about all day regardless of light and doesn’t nibble at the coral at all.

    Great fun particularly when he lifts up one arm of the starfish to clean him.

    I have two Fire Shrimp(s) in my 32 gallon Biocube. I put one in initially and it was a bit reclusive and established a cleaning station under a ledge that was at least visible. Then I read where having more than one made them more sociable. I bought another and after a five minute sparring match, they became best of companions and are out most of the day and eat like pigs. They share the tank with a Wheeler’s goby and it’s tiger pistol shrimp mate and there have been no issues at all. The only drawback, in my case, is one of them pesters a hairy mushroom after it discovered that the mushroom captures brine shrimp and provides an easy meal. They are definitely a beautiful addition to the tank.

    1. Barry, thanks for the comment and for sharing your experiences there with the social aspect. I also love that they learned to snag the easy meal from the mushroom :).
