Unexplained Fish Loss

[cali_reef]

What is the question? Why did you fish die or how they just vanished from your tank?

Fish dies, not one will be able to tell you why your fish died, especially if they were healthy looking one day, and is dead the next. As for the disappearing bodies, most dead fish in my tank are partially consumed by other fish as soon as they stop swimming, the rest gets devoured at night by the bristle warms and other scavenging creatures. I usually find a few bones under the rocks or back of the tank, water current tends to move them to the dead spots.

My tank is entirely enclosed, no gaps. There are no fans in my canopy or holes to vent hot air. This is one of the reasons that I have to run my chiller in the winter sometimes - bad planning on mine and Eric's parts. (The new tank set up has fans and vents.)

The question is why did the fish die. I know that sometimes they die for no reasons, which is why I wasn't particularly concerned when my blenny died. But to have two perfectly healthy seeming fish die so close in time to each other ...

Mostly, I don't want to restock anything until I have some idea of what could have happened and how I can fix the problem. It just seems irresponsible to do otherwise.

The death of the first fish sadden the second fish so much it took its own life. :skull:

Maybe they had a suicide pact.

Just set up the 40, and dose the rock before it goes into the new tank!

 

[ellebelle]

How? I don't want to do a FW dip on it all. What else could I do to it?

Dead spots huh?...:bigeyes2:

Maybe they went where elephants go to die?
Next time you go to Africa..don't be putting any thoughts into their heads!

Here is a photo of the crab I was talking about (someone else's photo, but EXACTLY the same crab)

I heard kitten knows how to dine with manner and even close the canopy back when done.:tongueani

That type of crab, with the dark tips, are know to eat zoa's and sometimes mushrooms too.

 

[ellebelle]

Which would explain why I was having a hard time keeping zoas for a while.

Lissa, sorry for the lost of your fish;(

Lissa - are you going to try the baited glass tonight?
Still pondering this..could you possibly have one of those nasty worms (not a bristleworm) that can kill fish? Thinking along those lines since the Blenny is a bottom dwelling fish and the wrasse sleeps on/near enough to the sandbed. The fish are fine and swimming and eating yet overnight they totally vanish...
From what I've read your Xanthid crab doesn't look like a candidate for murdering fish. If you had a Mantis in your tank, wouldn't you have seen a prior indication of it's presence by now? But a nasty worm, you might not ever even see him...

Anyone know how to make a homemade worm trap?

Eric hasn't suddenly put up another tank with a blenny & a wrasse has he ?

 

[ellebelle]

I've never heard of a worm that kills fish!
