Medusa slug

[anthonys51]

Bought one 8 days ago. Told it would eat detritus off the rocks. Today 3 fish are breathing heavy haven't seen the worm in days. I am currently running carbon and doing water changes. Can't fine the worm though

Test your ammonia, may have died and now there is an ammonia spike. Seachem Prime can help with the ammonia for now.

Try to find it, check over flows and behind/under rocks.

Total volume is 575 gallons. Don't think one medusa cucumber would cause ammonia spike enough to make fish breath fast. I would have to move 600lbs if rock. Do you think carbon is enough to stop it fir spreading to other fish if poison

Does anyone know if they release toxin all at once. If I can't find the body will it cause any more damage

could the cucumber have introduced a disease/parasite? im thinking the symptoms sound like it could be velvet or something similar...

are the fish eating?
do they have an visual sings of infection?

All 38 of the other fish are swimming and eating. Plus they looked completely normal on the outside. Only thing is there where laying on the bottom and breathing fast. Almost like ammonia poisoning

Cucumbers, boxfish, and some corals may release toxin if injured. Tang may have taken a tailswipe at it and triggered the problem. Carbon will ultimately get the problem, but you have to change the carbon every few days because it saturates and can't take any more. Likely the worm melted into goo.

 

[anthonys51]

I was going to change the carbon today then every 2 days 3 more times. Do you think that will be enough

The tail swipe might be possible. I didn't release it close to where the hippo likes to hang out. I saw the hippo tail swiping a hermit crab that was in its spot. Do you think leaving the body in does any more harm. I am assuming once dead it releases all its poison.

Net it out if you can spot it. Most of these things just melt. And yes, I'd change carbon every 2 days. It'll absorb most fastest, so often at first, then a greater number of days between changes. Be sure to wash the carbon to get the dust off: carbon dust is also harmful to some species.

Can't find it looked for hours. Don't want to take all my rocks out
I think I am past the danger zone but will change carbon out a few times just to be safe

Seems that variety is mostly non-toxic as it lacks the Cuvierian tubules

Me thinks you are making assumptions..
Not to mention you have a lot of water volume there..

Fair question

This is the one I have

Yes it is a lot of water but only 4 fish where affected. Maybe they swam into direct contact with the poison. Who knows. I also dosed 50ml of iron the same day. I been dosing once a week for past 3 months. Maybe the iron killed it

Yes

That's what I used. Msybe it was that. But I dosed before with it. I am throwing that stuff out just in case. Thank you

And are you testing for iron and using that to determine when to dose or just blindly dosing?
Have you always been dosing 50ml?

We also don't really know what/if anything in there is causing the fish deaths so that could be something you aren't testing for either thats now in sufficient quantities to cause the issue..
IMO stop dosing right away...
Its just too coincidental

Seachem could have had a bad batch or whatever..

 

[anthonys51]

the bottled said dose 125 ml a week for my size tank, i figured dosing 50ml a week cant hurt. but yes i will stop blindly dosing i know better

 

[anthonys51]

but could still be the slug, so will run carbon also cant hurt

Bottle also implies a freshwater aquarium..

And yes.. blindly dosing is never a good idea..
