New Fish Die within a week

[Grumblez]

I'm not sold on QT and treating all current fish if truly asymptomatic, but I would def consider doing one of these https://aquabiomics.com/

Dude, I'm asking for solutions. I understand your point which is the reason I'm here.

I've had a similar experience. Almost all of my fish have been in my tank for over 5 years some more than 8 and are all strong and healthy. I have tried adding a few over the last year or so and they last for a few weeks or so looking strong and then just are gone. I stopped trying to add fish.

I would put your current fish in QT and treat per Jay Hemdal's outline. Let your DT go fallow. Then, I would try a different fish store and QT them also.

I looked up Jay's posts and I didn't see his step-by-step. Do you have a link?

Current quarantine protocol

I am out of town and don't have my laptop and can't pull it with my tablet but I did find it. Email Jay if you still can't locate it.

Good Luck!

TANK UPDATE:

I've since upgraded to a newer 120g. I used a combo of saltwater from my trusted LFS and some RODI with mixed salt. It cycled and I started with a few chromis (I'm now up to 3.) THE SAME issue is happening in a completely new tank. New fish live a week or two (sometimes 3) and then die. I had a clown and bicolor angel who never seemed to eat so I get those. But I had a Powder Brown who was eating, moving, and looked great for 3 weeks and then died overnight. Now I have 3 Chromis and a Toby Box Puffer who is doing well.

I also have a half dozen coral frags (Duncan and some hard ones) that aren't doing well but a few (toadstool, Xenia, and torch) are ok.

If you look above in the post, you can see my acclimation process. I MIGHT try the suggested 2 fish (one in my display and one in QT)

Parameters:
Salinity: 36PTT (Trying to keep it closer to 35)
Temp: 79
PH: 8
NI: 0
NA: 0
Ammonia: 0
Phos: Between 0-.25 (Test kit isn't that specific)

My LFS pro is baffled.

The steps:

remove all fish from anyone’s tank that are dying

go fallow 80 days don’t do the short version, do the good job extra mile version

do not add anything wet from the pet store unless it goes through a separate fallow tank thereafter, read Jays article “biosecurity”


quarantine all fish minimum thirty days before adding and pre treat in quarantine any highly inclined species, read up during qt which species are best observed and which ones are best treated medically right off the bat


changing tanks did not remove disease components it transferred them, starve by fallow.
