Mass tank deaths overnight

[essex_lad]

Ok guys so here is a mystery for you to solve. This morning I woke up to find both my shrimps dead and my clown looking a bit worse for wear. I'm thinking my clown may have murdered them. What are your thoughts?

Victim A:
Had this fire shrimp for 2 weeks, been behaving normal only appearing from the rocks for food and giving the tang a little clean now and then.


Victim B:
Had this only 3 days. Used to clean the clown then stopped but still behaved normally.


The suspect:
Lost his partner last week to white spot. May be upset now. Havnt seen him go for the shrimp myself. Both sides of tail looks scared this morning.

Are there any other fish/inverts in the tank? how big is your tank? is there meat in the shells or have they just shed?

It was def the whole shrimp in the shells and the tank is 140l. I have a firefish, yellow tang, the clown and a little orange fish that is completely harmless. I also have 2 rosebud bubble anemone's and a few small corals.

Seems like you haven't gotten your shrimps for a long time. Only 2 weeks max - how was acclimation on them? Slow drip? Sometimes age and coincidences. I see you do have corals in your tank that seems to do well - otherwise, I suggest running some carbon/polyfilter pad to see if it's something else.

IMO I don't think the clowns did it. I've seen though where I lost shrimps easily too. I think because of buying a already 'sick/weak' shrimp, rough handling, bad acclimation.

Whatever is going on with that clown does not look like battle wounds to me.

How long have you had those fish?

 

[woodnaquanut]

Yes, that clown doesn't look healthy. Does it have a white film on it like it looks in the picture?

Marine velvet or Brooklynella?

Yes, that is my concern as well.

Would think whatever killed them would have been eating on them. The corpses look pretty pristine to me. I don't think it was murder. Natural causes or poisoning would be my guesses.

 

[humaguy]

yeah, not death by attack, they died due to illness, very sorry...need to treat the clown...

How old is this tank? How and when was it stocked?

 

[OrionN]

The Xenia looks bad, the fish looks bad and the shrimps are dead. I think there are problem with your tank and it is not the fish killing the shrimp.
It is not ammonia or nitrite because shrimps would tolerated these more than the fish. The tank looks brand new. Did you dose your tank with any medication?

 

[rjallen]

Ammonia spike???? Is this tank properly cycled? Ammonia will damage the kidneys/ liver and will have symptoms similar to Brook. I think this fish is a goner if I am right. Will take out the inverts as well.

The clown is looking much better, the tank is about 2 months old now and put my live stock in a month ago. Iv just had an out break of white spot that I have just treated.

 

[OrionN]

I am fairly sure it is the treatment. How did you treat the tank? With what med?

 

[essex_lad]

I used oodinex it's meant to be reef safe. My inverts and corals seem to be ok.

Most likely that is the problem.
