An interesting fact observation cleaner shrimp; Don't mix and match

I've tried to put several cleaner shrimp together in a single tank, but I've finally decided that it just can't be done. Once they hit maturity and start pairing up, only one pair will survive. All other shrimp 'mysteriously' disappear. I've asked other people over on MOFIB if they have had the same problem, and several people have indicated the same thing.

I've also noticed an even stranger phenomenon. If one of the pair dies, the one that is left will not pair up with a new cleaner shrimp. It would appear that these guys mate for life. I haven't read anything to indicate this, but I've lost at least 5 shrimp over the years just trying to put a new shrimp in with a lonely shrimp that lost it's mate.

If anyone has had any experience different than this, I'd love to hear about it.

You know, I have had seahorses like that. I had a mated pair for a few years, and they bred 6 generations of gorgeous fish. But, at the end, he died from old age, and then she would not eat. 2 weeks later, she expired.

It has happened more than once, but I really thought it was just my genus! I would have never thought inverts could be so people like.

I see it a lot in my real job. People who are together for decades seem to expire with in months of each other, with strong devastating injuries....

That is interesting! I wonder if they were introduced through a mesh if they would acclimate and mate.

While doing the research at the U yesterday, I ran across a paper that mentioned this phenomenon. I haven't read through it yet, but the abstract mentioned that cleaner shrimp pair up and peppermint shrimp don't. I don't know if it went into the possibility of pairing for life or not though. I'll let you know.

Like cichlids or clownfish, they pair up and get rid of any others? That would be cool to have a hobbyist (a scientist/hobbyist) find this out...

I had a coral banded that would go after anything that moved. Unless you have a pair you only put one to a tank. That is so interesting when you find out more I am interested in learning about these strange little creatures. They kind of freak me out, for many different reasons.

Coral banded shrimp are pretty interesting, Larry. They aren't that easy to pair up. First of all, they aren't hermaphrodites, so you have male and female shrimp. If you put the wrong sexes together, you will only have 1 shrimp in the morning. If you are lucky enough to get a pair (I can help you with that if you would like), then eventually the female will start to carry eggs. The eggs are a beautiful deep blue color and she holds them under her belly, just like cleaner and peppermint shrimp. She'll hold them for about 3 weeks and then release live babies into the tank. Then, the male kills her and eats her.

This doesn't always happen, but you may go through a couple of females before finding the perfect match. Once you find it, they can live happily ever after, for a few years. If there are other shrimp in the tank, however, they might disappear on the night the female releases her babies.

You read it here first. ;) If you read this in an abstract in the Zoological Record in 3 years, let me know.

Thanks Amie, I think you are the best. I think it is so cool when they shed their skin. The first time I saw that, it freaked me out. I thought I had a dead shrimp that something had just sucked the life out of. But there was the original in all his glory just hanging out, I guess waiting for his new skin to do something, I guess. So would you remove the male to protect the female and the young?

That's a really good questions that I don't know the answer to. If you knew the exact night that the larvae were going to be released, I guess you could remove her and put her in a quarantine-type tank for a day or two. Or maybe figure out a way to separate her within the same tank. Getting a pair that matches up perfectly is the best solution. We finally got a good mate for my mom's male coral banded shrimp. She's carrying eggs all the time and he hasn't killed her. He did kill previous females, and the 2 of them took out a couple of cleaner shrimp once, but they seem to be pretty happy now. I need to get a picture of her when she first has her eggs, they are such a pretty blue color.
