So, a couple of weeks ago I lost my YWG to that dreaded weird white spot that YWG apparently are prone too. The tank is fishless minus him. Does this certain bacteria live on in a fishless tank? I want to add another YWG for my pistol shrimp, but want to ensure it's safe. I don't want to risk killing others by dosing the DT with meds. Anybody have experience with this?
DT safe to add fish?

Assuming it was ich or velvet that took the life of your fish, then the tank will be free of the parasite if it remains fishless for 76 days. After that, you should have a "clean" tank for adding fish into. If your new fish arent treated/quarantined for anything they could be carrying when you purchase them, then you have a chance to re-infest your display tank.

Thanks a lot. Not sure WHAT it was. I kept reading that YWG are prone to this. Not sure if it's ich or velvet or another strand of bacteria. It lived about two weeks since I first saw it. Got him into quarantine a bit later than I should have, as I didn't have a QT tank (I've learned the hard way).

No sweat. Take a look in the Fish Disease forum for Humblefish's posts on treating Ich, and it will give more detail on the fallow period, if you are interested. Im not an expert on the goby, so I cant speak to them, but perhaps a post in that forum with a picture (if you have one) would give you a positive diagnosis, so you can better plan your fallow strategy. If it was bacterial, there may be a different approach to take.

76 days and any affected fish need to be in fully therapeutic levels of CP of Copper for a full 30 days before adding them to your DT

Well I lost the fish, and just want to get another buddy for my pistol shrimp. Just don't want to treat my tank and kill anything else.

@4FordFamily his goby had a bacterial infection while in the DT. I don't have any knowledge with your question @Adam113 so I'll tag those who would know.

I'm just going to copy and paste what I said in response to this same question in the other thread you have.
It's not really a "yellow watchman disease"... it's simply a bacterial infection. There are many many many types of bacteria in the water and it's the fish's immune system that keeps it from hurting the fish. So, yeah, the bacteria will always be there.... just like people in the real world. Bacteria is all around you on surfaces everywhere and in the air. Your immune system keeps you safe from them. Make sense?

So with bacterial infections, if I add a new fish, it's pretty much dependent on that one fish's immune system, regardless of what I do to the DT's water? I've just never had to deal with a sick fish since I started. It was pretty hard and depressing trying to nurse him back to health just to lose him
I do have a proper quarantine tank now though.

Harmful bacteria are almost always present in the water. Mostly gram-positive strains at low concentrations, easily beaten by a healthy fish's natural immune system. Like germs in the air.
Typically, only gram-negative bacteria (e.g. Septicemia, Aeromonas, Vibrio) are lethal to fish, and these strains are only brought in on newly caught fish (out of the ocean.) So, keeping these out of your DT is just another reason to QT.
One exception to the "gram-positive not being dangerous rule" is if the fish is already battling a preexisting parasitic or worm infestation. When this is in play, the immune system is already being taxed so anything else it has to deal with (such as a secondary bacterial infection) can prove to be too much.

Well... did a large water change, and got another YWG today. Requested a certain one that looked great at LFS. Got him home and in DT (again, a fishless tank besides him, so I'm not horribly worried about putting him directly in) and saw the other side of him that wasn't visible at LFS.
What do you guys think. Looks mighty similar, but almost more of an injury. I don't know. I'm getting disheartened with this. Might start up the QT or contact the LFS.

@Adam113 I'd yank him out and treat with antibiotics in QT: https://www.reef2reef.com/threads/antibiotics.283711/
Is this the same LFS you got the other one from?

Same LFS. Never had an issue with anything else I've gotten from them whatsoever. These YWG are my kryptonite I guess.
Doing it right this time. The little guy is in a proper QT and first dose is in.
@Adam113 I suspect both your LFS and your DT have lingering gram negative bacteria. I recommend at least a 30 day fallow period. Running a UV or diatom filter in your DT would be very beneficial at this point.

Will running carbon help at all? If not, is there a recommended cost efficient UV or diatom filter? I have zero experience with either.
Carbon won't help with this, but a DE filter might: https://www.reef2reef.com/threads/d...xternal-parasites.212429/page-15#post-3837188

So I'm dosing sulfaplex in my quarantine. The directions say to repeat dose every 3 days.
I'm doing water changes every day to keep ammonia down, and I'm replenishing the meds that I lose during my water changes. Do I ALSO repeat the original dose every three days on top of the dose already in the tank?

I wouldn't worry about replenishing the meds after a WC. Antibiotics mostly dissipate out of the water after 24 hrs anyway.
