What eats L amboinensis?

Postby Gregg » Fri Oct 15, 2010 8:24 am

In the 1990s I had a pair of L amboinensis in my 75g mixed reef that released larvae on a regular 7 day cycle (14 days for each shrimp). Never had much luck, couldn't get them past day 18 using Nanno, Rotifers and BBS. I haven't had any L amboinensis for about 10 years or so. I still have that same 75g mixed reef going. Tuesday night I picked up a pair of L amboinensis that were both about 1.5" in length, with the hopes of trying again. Did my standard slow acclimation over about an hour and released into my tank right as the sun was "setting" in the tank. Both looked good.

Early Wednesday morning before I left for work, and before the "sun rise" in the tank I could only see one, but it looked OK. When I got home from work Wednesday evening, I couldn't find either one...after thoroughly scouring the tank, I could see a couple of white antennae sticking out of my patch of mushrooms. After feeding the tank and still no sign of either, and the antennae not coming out of the mushrooms I reached in and pulled out the front half of a shrimp. The shrimp was bitten/chopped in half, right between the head and thorax. Antenna, eyes, mouth parts and legs were all undamaged. At first I hoped it was just part of a molt, but it definitely was not a molt, it was half of the shrimp, it still had the flesh inside.

Tank inhabitants are:

• 5" Yellow tang (Been in the tank since April 1995)
• 3.5" Pajama Cardinal (Been in the tank since 2000)
• "Hawaiian White Starfish" - possibly Ophiomastix sp. It looks like some sort of brittle star. It is pink/reddish with white spines. Central disc is approximately 1" diameter, arms are maybe 0.25 diameter near disc, about 6" in length. Been in the tank for about 8 years.
• Caulastera sp LPS
• 4 sp. of Mushrooms
• Green Star Polyps
• Two sp. of Zooanthid
• 3 Tree corals (unknown sp.)
• 3 pieces of plating Montipora sp.
• Blue Leg hermits
• various sp. of snails
• Live rock, added between 15 and 12 years ago, from various places including Florida, Fiji, Marshall Islands and Tonga that I know of
• 25 lbs live sand, and 25 lbs dry aragonite sand added 15 years ago

I know that the fauna in the tank is varied, I have lots of the asterina stars, limpets, and copepods on the glass, amphipods on/in the rock and various worms in the sand, including at least two different species of bristle worms, one red and the other a pale green with white setae. Plus, of course, who knows what I can't/don't see that may have grown in the sand/rock over the last 15 years.

What would eat L. amboinensis? I have some thoughts on this, but would like to hear any ideas anyone may have about this.

Thanks
Gregg

Gregg,

To answer your question..... anything that can get it in its mouth.

My $$$ would be on the Pyjama Cardinal allthough especially if only part of the shrimp was found.

I've had dottybacks take peppermint shrimp whoch are teh same same as them, they just break them into smaller pieces.

You only have 2 fish in your tank? But if the shrimp died in your tank because of some chemical imbalance that they can not adjust to, then your worms would be able to consume the bodies within hours. Have you been running the same 75 gallon tank for over 10 years without any crashes? How often do you do water chances, how big are they and what kinds of chemicals do you dose with?


I've had a hawkfish kill a few of them, so I'm not sure the mouth size is always a great test.

There's no way that either of those fish were the culprit. If you had a mantis, you would hear a clicking noise periodically. Maybe you have a rock crab that has grown over the years? Can you test your alkalinity and iodine levels? If those are fine, I'm stumped.

Nope...not those mushrooms. Some big huge fuzzy's, maybe. Paul, Dottybacks can be MEAN. I had forgot, until reading your post, that I had a dottyback kill a shrimp once as well. They are impossible to get out of your tank once they are in, smart #$%^£@* fish.
