Healthy fish getting missing one after another just overnight

[TonyL]

Hi snr,

Anyone can advise why healthy fish missing one after another, I suspected Crabs and started to trap them. So far caught a few small hairy crab not bigger than 1/2 inch. However still have fish missing. First is my 1" Blue Tang, Next was my 2" Flame Angel. And another 3 smaller fishes. All eating and very healthy fishes. No trace of their remain etc....I suspect some BIG hitchhiker

Yesterday, I took out every pcs of LF and dip into Fresh Water, again manage to catch 3 small hairy crab. I hope that the end of my era. Pray hard....

Or anyone have similar experience and can share your removal method....thks

regards

TonyL

Hope it is not the work of ISOPODs.

No....that why I have no clue. Even my 4inch Clam was tear apart left only on side which I believe will not survive as well. I did a fresh water dip for everything in the tank to get rid of all the hitchhikers. but like I mentioned only a few miserable small hairy crab which is less than 1/2 inches. My Flame is 2.5 inch and I don't think the small crab are the culprit. No remain nothing at all when I take down my whole tank. Septicle to buy any more fish....Sian.

Anyway, thanks for all the advise.

Can a mantis shrimp eat clownfish?

[TonyL]

I believe they can whereas crabs can only grab those fishes that sleep between rocks gap. like Blue tang etc...So far my 2 clown fish still around. As they hover mid water when sleeping. Touch wood...

Hi all,

Latest update, I believ e after all the fresh water dip I think i get rid of all the hitchhiker. 10 days past and seems ok. thanks to all for the advise.

Fresh water dip dont kill them..only stun them.. U need to remove n check 1 by one. Unless u left ur rock in fresh water for days that will kill ur rock also..

Either you do a 1 week water dip or cook every rocks you have

I have a very big and healthy Naso. Yesterday saw him hiding behind rocks. I find his action is weird as he is so listless. Than I tried to make him out to the open space and I saw a ISOPODs on his body I quickly caught him and remove the pods and put him in a separate tank. Hope he recover.

My experience is that fish disappeared may not be due to Mantis or crabs. It may die to ISOPODs which weaken the immunity and caused other virus to kill them. Then the clean up crew will eat them up.

Hope my sharing will gove some ideas that pods do kill fish as well

Just to share once I found my 6 line wrasse dead. After scooping the body out, an isopod crawled out from its gill!

Could be when u bought it, its already in the fish gill. Hope fully thats the only one.

Hi all,

Yes minireefer is right, I say it too early. My rock scape been move again.

[TonyL]

Oops forget to add Corals also been push down. Seriously, I don't know what monster is inside there....Sian

Will Isopod diminish a 2" fish overnight. No corpse ...Nothing.

[klim]

Isopods don't eat fish, what they do is suck the blood out from fish. Whether it is 1" or 7", it still can attack. The body may be eaten by cleaner crew or other fishes. Mantis do attack and eat.

Caught this fellow in my mushroom rock during qt.. and operation on rock. This is the reason why i dont keep rocks in tank unless no choice. I normally break the rocks n glue the corals on a small rock.
