Help me solve the mystery of my snail deaths

Recommended Posts

Do me a favor and put the animal in an isolated jar with a snail to see if you are after the correct killer, it'd be a shame to kill a bunch of animals for nothing, chances are it wasn't the worm since worms really aren't too choosy of specifically sized individual snails. Fish on the other hand are able to be more choosy and the wrasse as suggested earlier could be your actual killer.

Dude. I usually like to let people be, but this is getting annoying. I understand where you're coming from to respect/preserve life. Even life that isn't thought of favorably. I really do. I also know that mother nature doesn't care about an individual life. It is so full of life, that it recycles life from one form to another via eating, decomosition, etc. That flatworm you want to save? It ate snails. Now the snail is dead. Should we try to preserve the snail or the flatworm? which life is more valuable? What about the frozen mysis we feed? Or pellets - that used to be living.

 

You can't save everything Amphipod. We play mother nature every day with these aquaiums. And playing god means we get to decide what's best for our entire glass box ecosystem. Jabeuy has been around for a while. Read his posts--you can tell he's not the type of person you imply above who wouldn't respect life.

 

There is already evidence this flatworm eats snails. Mine, for one. It's also all over the internet that they eat mollusks--including snails.

The worm was idenitifed as a leopard polyclad flatworm with via picture. The wikipedia link you sent is incomplete - notice that it lists all polyclad flatworms with a max 20 mm length? It's NOT talking about this worm. This flatworm evolved to eat clams, without clams, it eats snails.

Polar, you did not get what I was getting at, if the worm is the true killer, his innocence won't hold with his food source, in this case you think it is the snail, but the worm won't discriminate very much about the size of his food, if on the other hand it is the wrasse, the worms would have been killed for absolutely nothing.

There are dozens of species of polyclads that look extremely similar to what your picture shows, many times they are told apart from extremely minor differences we normally won't notice, but the minor differences in shape can sometimes have no effect on drastic differences in behavior

Sorry jabeuy. Every where I turn lately this one is sharing partial or mis-information and apparently I've had enough. Apologies if I was rude, Amphipod.

Does it look anything like this?

I grabbed it with tongs, but only got half of it. They regenerate apparently.

She is actually good looking.

I am curious how effective is she as a predator and tools she uses to hunt and kill.

Looks like it could be a bullseye. Honestly, I never heard about this worm. Probably wasn't looking hard enough.

Great find and info.

They're pretty fascinating once you get over the creep factor, especially how they move--it's surprisingly fast. I dug up some of the videos bookmarked, the second one is the best, IMO:

This is another type, but too funny not to share:

I had a polyclad flatworm before. I had to tear down my tank to get it out. Glad you had an easier time jabeuy.

How many of these worms do you think you have Jabeuy?

Another reason its not the worms is how the killing has abruptly stopped

About 3 or 4 of these that Polar found pictures of:

And then 1 or 2 of these guys that I see very rarely (but was able to get video of in my old tank):

The "clear" ones in the video, since I 1st started lol. Must have come from the live rock I used to start up.

 

The other kind, probably 2 or 3 months ago I noticed. No clue where they came from.

So yeah unless you have hoardes of clams mussels or similar easily accessible sessile molluscs out of your sight in the tank (which I am 100% certain there is not) they are basically forced to be innocent. Also since worms don't particularly enjoy many months of fasting and aren't very choosy of what to kill if its on the menu, they basically go by a first come first devoured basis, many of your snails should have been killed many months ago if the worms were guilty. It has to be something else, any other potential clues?
