If a fish is given a "recommended tank size", how much of that space (if any) can be considered "community water". For instance, I am looking to stock a 75gal tank with several large fish that are given a recommended tank size of 70+ gallons.. but is that 70 gallons that the fish needs all to itself, or can it share some of that space with little fishy friends?
The FOWLR setup I would like to go with includes:
1- Humu Rectangle Triggerfish
1- Banana Wrasse
1- Blue Girdled Angel
1- Blue Tang
-I am also considering substituting the Tang (because I know they need a lot of room) with something my wife would really like, such as a large Clownfish and/or a large Spiny Box Puffer, but I'm not sure if they would be able to survive with the other more aggressive fish.
I'm probably trying to make too much of the space I have, but If anyone thinks that it might work, please let me know..
...and maybe someone can shed some light on my question regarding fish sharing their recommended living space.
