I had a few people ask, so I wanted to expand on how I handle new fish. I have a few tanks with some softies and just for new fish introductions - 50g lowbow that I keep my colorado sunbursts in, 40 breeder and about a 80g frag tank that pretty much just does fish anymore. These all have sand and real live rock. I keep the parameters at reef levels with full clean up crew, water changes, carbonate & calcium dosing and traces. I have a few nice fish that are the welcome party. In one tank, I have a small blue angelfish, a few nice damsels and smaller powder brown tang - the blue is about ready to be moved on... it is starting to grow quickly. In another, it is a ORA (or some sort of captive) orange lined rabbitfish and recently a small female watanabei angelfish. These are my walmart greeters. I have the rock stacked up to where the fish can get away and hide completely, if they want - no caves, arches, PVC or unnatural stuff made for us. These welcome fish come to the top when they see me and eat out of my hand. The new fish quickly follow their lead and usually within a week, all new additions are doing the same thing at least for frozen and usually pellets and flake too. Once they grow a bit and will fight for flake, pellets and frozen, as well as not being scared of me, they can go into a larger tank. If they are passive eaters or not eating more than one food, they stay longer.
I never do copper or hypo or anything. If I get an angelfish from a unknown indo source, I do dip for flukes outside of the tank.
My tips for healthy fish:
In the end, I would recommend a pack of live rock in the display or welcome tank to at least supplement your QT. 50 lbs at 7 a pound and some air freight is probably $400-450 which is like 3 or 4 dead fish anymore. Get some substrate and let the critters on that rock spread for 3 or 4 months. Then, there are nearly no places for disease to hide - it has to fight to survive too. It is just a good investment, IMO.

My tips for healthy fish:
- Buy direct from the diver, if you can. This is easy with Atlantic fish, but has been a struggle since Hawaii has been shut down. I used to get the best fish out of Honolulu. Research your LFSs wholesaler and see if you like how they treat their fish - I like my fish to stay at 35ppt or full strength reef water. I don't like my fish to have been in copper at the wholesaler, or at least not my wrasses, butterflies and a few others. If they have been in copper, I want to know the level, but I usually avoid these.
- Captive Bred fish are a good.
- Have a welcome fish to show your new fish how to act in captivity. Keep your welcome fish well fed and having no reason to be jerks.
- Real hiding spots work better. I just pile up live rock and let them fully escape. Painted tank backs and sides seem to help too.
- Varied diet - duh
- I would have a welcome tank with sand, rocks and whole ecosystem to welcome new fish. If you want to do hypo or copper, then do that later once the fish are healthy and eating well. I do this for corals too... dips and stuff later on once they adjust. Unless you are going to have a full-blown coral, invert, rock, etc. QT, then I don't see the point of meds or hypo on fish if you can otherwise get them comfortable.
- If I am getting a new fish that needs pods, like leopard wrasses (my favorites) or a copperband, then I make sure that the tanks have not had similar fish for a few weeks and you can see the live rock, sand and glass covered with pods. This way, they can hunt for a while if they don't want to eat prepared food right away. My most recent blue-star leopard ate flake after about 3-4 days thanks to my walmart greeters, but still had a full belly of pods from the tank.
- If I get a fish with some rot or damage, I don't do anything but feed them. I used to turn up the temperature, but I stopped doing this. I use no meds. I recently got a Chocolate and Sailfin tang with really bad fin rot and damage to the gills from a local hobbyist who had no idea how to take care of them. It took a few weeks, but they both got better. I would not risk my other fish with a treatment, and have never really needed to. These two fish were not in my plans, so they have since gone on to a new home and are doing well.
- The fish being comfortable has been better for me than medications or hypo. I tried to think of the last time that I lost a new fish and it has been many years. I have had a few jump, which is no less painful.

It took me a week of hard work and maintenance to get things stable again. And now everything is thriving. The important thing is to not quit.
