The difference between a 125 and a 180?

  • We are currently upgrading MFK. thanks! -neo
A 6 foot 125 is 18 wide and a 6 foot 180 would be 24 wide. I think its also a few inches taller
 
125g 72"*18"*21"
180g 72"*24"*25"
 
I know the extra 6 inches width will make a big difference in making the fish more comfortable
 
125 is meant for lots of smaller fish, 180 is mostly for a few large fish.
narrow tanks are mostly for small community fish
 
A 180 can house some nice clownloaches and geophagus :) a 125 can house some nice flowerhorns :headbang2

overall in general, 125g can house fishes ranging from 1" - 15" max.
180g can house fishes ranging from 1" - 20" max. they should be comfortable in being able to turn. shouldn't get fish that maxes out at 24" because they will feel stuffed.
