What is the smallest corydoras catfish commonly available? The reason i'm asking is because i just got my younger sister her very first aquarium for x-mas and was looking for some neat and cute bottom dwelling fish to scavenge left over bits of food. The size of the aquarium is 6 gallons and i know that cories like to be in groups. I just wasn't sure if this would be a good choice of not. Also, what other fish would you suggest? I was thinking guppies or other small livebearers. I don't have alot of experience in FW thought i have a good deal of experience with SW and was thinking about what would be good hardy fish that look nice and are fun to keep her intrigued in the hobby and hopefully get her more interested in it to get even bigger fish tanks and deal with fish for the more experienced hobbyist
. All of your input is greatly appreciated.
thanks again
