Mayday! Clowns look terrible

[outtafocus]

Sadly the clowns did not make through the night. Both were dead this morning. I'm sad.

I believe it was brooklynella, as the symptoms match what was posted above. Colour had faded alot, black strips were a light brown, the orange looked pale. They also had a nasty film on them.

As for the 2gal QT. I had posted in a previous ich thread if a 2gal Qt would be ok to use. I was told it would be ok. They would have been in a 10gal, but a friend borrowed it as a temporary home for her turtle.

It was a rookie mistake to not even think about some kind of biological filter. The entire quarentine process was such a knee jerk reaction for me that I must have just let that bit slip.

I will be waiting a long time before I buy any further fish. I feel I have more research to do. I thought I had enough knowledge to safely buy a fish or two, but this shows I have a long way to go.

When I do decide to buy fish again, they will be going straight into a 10gal QT, however, what should be used as a bio filter? The copper solution will kill anything on live rock.
Suggestions?
