Need Centerpiece fish

[bkiggy]

I have rehomed fish and added new, but my tank is now 'missing something' - here is the stock - 15 diff species of Cory's, Pleco, 2 upside down catfish, alot of beautiful guppies (rehoming some females)(got too big) and 1 male elephant ear Betta

40 gallon , all live plants
Fluval 406
I rehomed my African Butterfly
I rehomed my beloved Pictus catfish

I need something cool !!!!!!
The guppies are food hogs , the Corys get what's left, so my new additions will have to be able to hold their own !!

Almost all of guppies have died. Looking for something cool. And colorful
