Looking to trade my 2 Firemouths into my LFS next week. I've narrowed it down to 3 replacment possibilites for a 29 gal. established tank. Which of the 3 would you suggest? I'm looking for something somewhat active and very colorful and bright. Pretty and deep rich colors are a must. Activity is nego. as long as that won't hide behind a rock and never come out. That dog will not hunt. I know, I know, if you want good colors get a saltwater tank but I can't afford that. Whatcha'll tink?
