Which fish next - Bengaii Cardinal or Yellow Coris Wrasse?

....Or could I add both at the same time?

I recently had a Royal Gramma with Ich (which died) so all my other fish have been in a QT for about 5 weeks now (treating with Cupramine the first 14 days).
I'm about to move them back to the DT in a few weeks(2 Ocellaris Clowns and a Bicolor Blennny) and I would like to stock 2 more fish after that.

I know you should stock the most aggressive fish last but neither of these are considered aggressive. My QT tank is a 20 gallon long so would it be possible to get BOTH fish and go through one round of quarantine for 3 to 4 weeks instead of doing this separately back to back? Or if I should get them one at a time and which one should be first and which second?

These will be the last two I stock as my DT is only a 37 Gallon tall with a few Acans, Candy Canes, a branching Hammer and some Zoas so I don't want to get too crowded.

FWIW this tank was established 5 months ago and remains stable. It was established by combining two other smaller tanks that were each established for about a year.

need about 4 more weeks of fish free DT

need about 4 more weeks of fish free DT

I was thinking 3 more weeks puts me at 8 weeks of quarantine and I thought tha was enough but another week is no big deal.

I'm trying to plan ahead for when I am finally done with QT in September.

12 weeks min fallow and still no guarantee.

Alright. I want to make sure I do this right. SO forget about the fish addition question.
For now the daily water changes are killing me so I'm going to set up a FOWLR 40 gallon breeder. It will probably take 30 days to get everything cycled (using cured rock) and fully self sufficient but then I'll move my fish into there.
I'll leave my existing display tank as a reef only tank and just maintain my corals there. If I hold off for 20 weeks total that will take me till just before Christmas. I can manage that long if I have a tank with natural filtration. But I can't maintain these daily water changes that long in my hospital tank so its just time to move on to another tank.

I've been at this for a year, starting with a Biocube 14, then the 20 gallon breeder and now the 37 tall I use now and never had an problem in all this time. I quarantined with Cupramine every fish that came in so only thing I can figure is that it came in on an invert

I think you could qt both together in the 20 long but I think the 37 tall is too small a footprint for the yellow coris. A very active fish.

yes..anything hard including rock can bring the ich into the tank..
do not add anything new to tank while during fallow period.
good luck...
