12 Gallon should be fine for a small Jawfish. The first one died the same way but in my main tank, and there is defiantly not a problem with that.

Did all the tests the day before when he did not eat,and ran all the test when I found him dead. Looked like he had just died so I don't think it had time to foul the tank yet.
If you look at the pictures he still looks good for a dead fish, and he defiantly did not starve to death.
I wonder how many of us loose fish that we have no idea what happened.:cry:
The first one I thought nothing of as in this hobby it happens, but two times exactly the same way I find strange.

I don't think so it is a broad spectrum that covers a lot of nasties.
You can use it to dip and to treat them daily. It dissipates over time and I only used it for the first two days and not at full strength.
I ran carbon after the two days as well and did a water change on day four so don't think this was the case.
I would like to know wonder if I can send him somewhere to have tested?
I put him in the fridge for now.

What other inhabitants do you have ? They do not take harassment at all. They will just hide/quit eating and will die just from the stress alone.

But what does safeguard do to the cycled bacteria? Just a thought.

First one just a black clown fish in the main tank.
2nd was in QT a by himself in a quiet space.

If that was a problem it should have spiked my No2 - No3
Test never indicated a problem and No3 was at 5 ppm so I think the cycle was still there, but its hard to know what happens on a micro level.
I an not a fan of medication to begin with, but was a bit paranoid after loosing the first one.

Clowns can get real territorial, especially in smaller systems.....
sucks to see a 400 dollar loss with no solid evidence of a reason.

did you get these @ JL?
I know they had some (still have one) and they looked awesome....

I've had mine for just over 2 yrs, they are really entertaining. Boy they sure have climbed in price, though not cheap back then either.
