New fish with Ich (in quarintine) never in main tank

Got a Bicolor Dottyback from the LFS and noticed a white dot by his eye on the car ride home. Fortunately I had been setting up a pico tank (in addition to my main tank), so I put him in there as soon as I got home. The next day I started treating with "Ich Attack". I noticed after putting him in the pico tank, he had small dots on his fins as well. He is looking allot better, no Ich on his fins and the spot by his eye is almost gone. After reading up on ich I realize should have had no sand or LR in the tank, but unfortunetly this was the setup I had in place already.

My question is when is it "safe" to put him into the main tank? 7 days of treatment will be over on Sunday and I was going to do a 100% water change (easy in a pico tank). I was thinking an extra week? So 1 week of treatment and 1 week after in the pico to make sure.

I REALLY don't want to contaminant the main tank and my other fish, so I'd rather do whatever the safest option is.

 

A week is probably the minimum. When I had my 75 I quarantined a blue hippo for seven days, put him back in the DT and then had to put him back into quarantine after a couple days. If the symptoms have completely disappeared, wait a few more days to be on the safe side.

 

i would wait about two weeks after final treatment just to be sure

 

The product you are using does not kill ich effectively. Unless you treat the fish with either

Copper
Formalin
Hyposalinity

Once you introduce that dottyback to the display it will carry the parasite if it is indeed ich.

Just the facts..........

 

Stress can also make fish looks like they have ich.

 

If a fish is stressed it may succumb to the parasite. If it looks like ich than it mostly like is and if not than brookynella.
