Description: I have 5 comet goldfish and 1 koi. The tank has two canister filters and two additional air pumps and 12" air wands. I am using river Rock for my gravel so my fish won't eat it, and some plastic aquarium decor. I also have 2 bristle nose plecos, 1 Chinese algae eater and several Cory cats.
Advice: Goldfish and koi tanks require more frequent cleaning and better filtration.
About Yourself: I started with a small goldfish and koi pond but after it was destroyed twice by muskrats I moved my fish indoors. I love it. Goldfish and koi are very personable and fun to hand feed. I raised a butterfly koi from 5" to a whopping 27" and it out grew my tank. I donated her to a koi farm nearby and now I am starting over.
