The symbiosis between gobies and pistol shrimp is one of the many that can occur in our marine aquariums. In the goby and pistol shrimp symbiosis, both. If I put in a pistol shrimp, do you think that one of the gobies would pair up with it? I love watching the relationship between pistol shrimp and. Genus Stonogobiops - Symbiotic Gobies, The Pinnacle of Symbiosis in the Tropical commensal and mutualistic—the shrimp goby-pistol shrimp relationship is a fishes or other substrate dwelling fishes (e.g., jawfishes, engineer gobies).

It never caused any trouble, at least that's what I was thinking until I found out what was killing my Cleaner shrimps. I've seen the pistol cleaning my Yellow tang once, but as far as I know, Pistols are not known to be cleaners I also have another question: Would it be a risky game to add a dwarf lionfish?

Merci beaucoup for your help! Do bear in mind Alpheidae are all predatory to some degree, and will view smaller invertebrates as prey. The species I maintained under lab conditions coldwater species from California were incredibly hardy and held their own very well with crabs of equal size. While I dare say they'll mix fine with somewhat larger, fast-moving midwater fish, I wouldn't personally recommend combining them with anything small or slow.

As for your 65 gallon system, assuming water quality is acceptable, it doesn't sound overstocked to me. But I wouldn't recommend adding anything else. Is he dangerous for the grass shrimps??? In time the eel will take care of the shrimp! I have done some research, but I'm getting mixed opinions as to compatibility with fish. Is this an Alpheus immaculatus? An "anemone" pistol shrimp? This species is reported to be non-fish friendly I would like to attempt to "match" the Goby with a Pistol shrimp I know it is a crap-shoot.

Somehow your answer did not get to me via e-mail, but I did see it in the "daily questions" section. Now that I know what it is, I'll do some more research. What I'm seeing so far is that it is not that common a shrimp and not much "captive" information is known. I can usually find an answer to my questions by browsing through your extensive "library" of information.

However, I haven't seen this one! The shrimp dug out a burrow in the four to five inches of fine sand I have in a 28g aquarium.

The Goby moved in but then I actually observed the shrimp pinch the Goby on the lip. I thought the pistol shrimp expired. The Goby seemed to "forgive" him for the rough behavior and moved in to the new burrow.

One day I saw my Red Firefish backed into the same burrow. Then the Goby's tail fins suffered the same fate once again. Again, a cave-in of the burrow and the Pistol has not been seen in over a month.

I am wondering if I should be feeding the Pistol Shrimp something specific so he doesn't "pick" at the Goby? Do Pistol Shrimp lay dormant or hibernate for a period of time?

I volunteered to adopt this pistol shrimp in hopes of the shrimp pairing up with my small Valenciennea puellaris goby, which is approximately 2.

The Symbiotic Relationship Between Gobies And Pistol Shrimp

Here's where my questions begin: The health and well being of my goby is of the utmost importance, as his crazy antics and silly personality have made him like family to me. Is there a reasonable chance that the Pistol Shrimp could harm him? Also, what are the chances of this goby pairing up with a Caribbean pistol shrimp? If I remember right V. I'm thinking the pairing up would be slim, but you never know.

Pistol shrimp generally pair up with Amblyeleotris or Stonogobiops Gobies. Will they eat Sexy Shrimp as well? This is an amazing partnership, but what goes on inside of the burrow that they both inhabit?

Until recently, we have only been able to observe their behavior outside of their elaborate burrows. I have been able to make some new observations with an interesting tank setup. First I will tell you the history of studying this particular symbiosis, then I will let you know how you can set up a tank specifically for viewing this symbiosis, and then I will relate my new findings. A Scientific History Luther, when he was a junior scientist, managed to catch a goby and pistol shrimp pair and put them in a small fish aquarium after they had been discovered during a expedition of the Red Sea.

Indeed it took a lot of time until these peculiar couples were back in scientific focus. It was again in the Red Sea, and the same species of fish and shrimp that came to the awareness of biologist Ilan Karplus in the s and s.

He and his associates studied how these animals communicate, their territorial behavior, the dynamics of building the burrows and the distribution of the different species. Observing them in nature by diving was difficult at best; scientists could lay down in front of the burrow entrances until their air ran out.

The Symbiotic Relationship Between Gobies And Pistol Shrimp

It took a long time to observe them because any disturbance caused them to stay inside the burrow for hours. Everyone who has tried to take pictures of them in nature is aware of this. Today we know that the symbiosis between gobies and pistol shrimp is an evolutionary model of success.

The majority of these are found in the Indo-Pacific and adjacent regions. There are goby generalists that live together with different shrimp, but there are also specialists living with just one species Karplus et al.

Species differ concerning the distribution of their partners, their age and sort of substrate different gobies prefer finer or more coarse sediment. Shrimp leave the burrows only during daylight in company with the gobies. Shrimp or gobies never lived alone in a burrow, and the minimum count was a single shrimp and a single goby. More often, a couple of gobies and a couple of shrimp were found in one burrow. To observe the association in aquaria was another approach to find out more.

The partners had to find each other in a Y-shaped testing channel, either by optical or olfactory abilities. The shrimp did not show any optical orientation at all, but the gobies did. Gobies could differentiate potential partner shrimp by sight Karplus et al. If unsuitable partners were presented in experiments, the gobies stayed away.

In reverse, the shrimp found their partners by smell. There was interest from the beginning about what the burrow looked like, but all that was visible from outside was the entrance. The tubes were filled with sand before the experiment started. After the shrimp excavated the tubes, the partnership could be viewed. This setup, however, appeared too artificial to me. Yanagisawa even poured resin into burrow openings in the wild.

The burrows went down as far as 1. The burrow often divided, and the tunnels extended into chamberlike structures.

Larger coral rubble pieces or skeleton parts of sand dollars were integrated into the burrow. My Observations These trials to find out more about the burrow system just fueled my interest to find out what was really going on inside.

Among marine aquarists, it was not even known that couples of shrimp and couples of gobies naturally live together. Most aquarists were happy to have one shrimp and one goby in their tank combined. Where and how would they reproduce? Existing observation did not have an answer for this question. But how could I look inside the burrow? I noticed that the shrimp tended to build their burrows along the bottom glass of the tanks.

Steady beating of the abdominal appendages pleopods kept the bottom glass free of sediment. So I set up a gallon tank on a high rack, enabling me to sit below and to observe them through the bottom glass of the tank. The frame of the rack just held the tank around its circumference. To reduce any potential negative impact from light below, I covered my observation chamber with a black curtain. I took videos or pictures with just a little light that I could switch on.

Both species were caught and imported in larger numbers together from Sri Lanka.

Amalgamating the couples of fish and shrimp was not an easy task. If same sexes are in a small tank, it often ends in severe trouble—the shrimp are able to kill each other in an aquarium. Therefore I kept them as far apart as possible in separate tanks until I could identify the sexes of the shrimp female shrimp have a more broad abdomen and more broad pleopods.

I also kept the young gobies separated. By changing the partners in one tank, I could easily find out if two specimens would go together, which is the indication for different sexes. In the next step, I brought both couples together in the observation tank. I kept the interior of the tank simple: The shrimp started building the burrow immediately after I introduced them in a little cup and directed them into a gap I made under a piece of live rock.

Then the fish were added. It did not take longer than an hour, and the double couple was together. During the next days, the burrow grew. The shrimp transported all excavated material and pushed it outside the burrow. They used their claws to push the sand like a little bulldozer. This astonishing skill can only be performed if the goby is out to guard their safety.

When the tunnel system grew, the partner behaved differently under subterranean conditions. The narrow space in the burrow causes them to squeeze their partners against the burrow wall. The fish tend to wiggle through the burrows with force and no hesitation toward their crustacean partners.

Due to the action, parts of the burrow system would often collapse. A fish buried under sand stays there without panic the shrimp can smell it and waits until the shrimp digs it out and begins to repair the burrow. The main way into the burrow can be up to 2 feet long during the first days of excavation.

Soon after, side ways are constructed, which can be as short as 2 inches.
