30g long. Ideal for QT. Any larger and you just waste money on medication.
I have dividers to partition the system. I'll be QTing lots of tangs for my own system too.
It would be ideal to source the fish as juveniles, in that case tank space will be less of a problem in terms of swimming room, aggression, filtration, etc. This is especially the case with tangs.
I have a pretty big inventory of food for herbivores too.
I don't know what tangs or other fish you'll be keeping so I can't really recommend how to go about adding them. Again, feel free to PM me and we can discuss this in more detail via text.
