Not too bad. It would be $8.99 for that, but I bought it at wag.com and they had a 25% off your first order coupon which put it at $5.99, and shipping was $5. There's more expensive foods out there, but many people use this. It's expensive because it has like no filler ingredients and apparently it helps fish keep their color really well.
Nah just freshwater. I might have a smaller saltwater tank this summer when I (hopefully) get a 55g for my New World Cichlids. My only fish tank at the moment is a 29g. Do you have any?
