Next Fish

[Chris Gunter]

I currently have a 55 gallon aquarium. I have four fish:
Maroon clown fish (about 4 inches)
Orchid Dottyback (about 2 inches)
6 Line Wrassie (about 2 inches) and
a Coral Angelfish (about 2.5 inches)

I would like to add another fish to the tank and wanted to get
peoples opinion about what they thought would be a good fish to add
to this tank. I do not have any corals. I do have 2 cleaner
shrimp. I would prefer to add a fish that can survive off of flake
food only, but this is not a have to have. I have thought about a
blue damsel, but I am worried the damsel might get too mean and rule
the tank. However, all of my other fish are fairly mean so maybe it
would even out. I have also thought about a yellow tang. Which I
think would do well, but I would have to feed it some algae and I
don't really want that complexity. Can you think of any other fish
that would be good and why?

Thanks,
Chris
