i'm new to QT so would 6 weeks be safer? should i go longer?
There are lots of different quarantine protocols that people follow and have success with. I don't think that there is any one and only correct way. For me, whether or not longer is better, would depend on the fish and the quarantine setup.
The following is what I do for quarantine, not for everyone, but it has worked very well for me. I have a quarantine tank that is setup 24/7 for fish. What I am using now is a 40G, if I were quarantining any larger or very active fish I would use a larger tank. The tank has a sand bed, well established live rock, and a few snails. I feed the tank regularly for the snails and to keep the biological filter active.
When I get new fish, I put them in this tank. Once they have started eating and behaving normally, I treat with two rounds of praziquantel. Most of the fish I have quarantined this way start eating within a few days, often sooner, so they are done with the praziquantel treatment about three weeks after I get them.
Then I observe them in the quarantine tank for a minimum of four weeks. If during that time I don't see any signs of disease and they are eating well, they move to the DT. If at any point they get sick, I move them to a hospital tank with no live rock or sand and treat appropriately. Once they are over the disease they go back to the quarantine tank and I observe them for a minimum of four more weeks.
I know that this may be overkill, but I have fish that I don't want to lose, so I don't take many chances. Any fish that I quarantine spends a minimum of six weeks, and it usually winds up being more like eight before they move to the DT.
