QT Tank Size Question

[itz frank]

I have an ich issue to deal with. Planning on treating it with TTM.

I have: two clowns, two wrasse, two cardinals, one fire fish, two blennies, and a gen. angel(3").

I don't have much space to house the tanks. I know bigger is better but the largest of my choices for tanks(40 breeder) will probably be need to be house in a seperate room. Where as the other two options 20L and 29gal can be housed within stand making it easier to get water from the display for water changes.

So, what would you choose?
40 breeder
29 gal
20L

These will be used moving forward for QT. So a 40 breeder might be excessive for a blenny.

From a QT standpoint, I would think it would be better to have your QT tank away from your DT (like in another room) as a way to prevent accidental cross contamination.
Just my two cents...

+1. also don't use water from the display tank that has ich.
