The tomato clown will get huge once it becomes a 'she'. Not saying you shouldn't have another fish, just saying be prepared.
 
ya i know... but hopefully buy the time the tomatoe gets huge i will most likely have a bigger tank...

soo was that a no due to the size of the tomatoe clown will get?
 
Nah.. just be prepared to move her to another tank :)

I know it's old school, but how about using the 1" of fish per 5 gallons of water?
 
my tomato is super aggressive---just got aggressive one day. He chases everyone around the tank. I imagine it would be harder to run away from a bully in a smaller tank.
