Fish for 100 Gallon and LESS Sized Tanks

[Ninja1]

Lets keep this simple and clean: list the name of a fish, a picture and possibly a comment about the fish that is suitable for 100gallon sized tanks or less. This should be very helpful for those who simply want to go to one place to look at the different types of fish they can keep in their system.

Please limit your posting comments in this thread and take the time to add a fish and its pic in your post.

For new reefers like me, please note that the length and space in the tank are also important to look at when you consider a fish. Some fish like to swim a lot and I've read that the fish enjoy longer tanks vs the depth. This thread is more about the size of the real estate for the new fish

The tank size is generalized by assuming:
55 Gallon = 48 x 13 x 20
65 Gallon = 36 x 18 x 24
75 Gallon = 48 x 18 x 20
90 Gallon = 48 x 18 x 24
110 Gallon = 48 x 18 x 29

I'll start first:
Clownfish : Best suitable for 30 Gallon + Sized Tanks. They tend to be aggressive with other clowns.

Ok, lets keep it going!

Is that a P. tuka anthias? I certainly wouldn't recommend it for a beginner, most experienced aquarists can't keep that fish alive.

Not recommending for skill level- more for what's Te appropriate sized tank.
