Here’s an interesting alternative to your usual aquarium ideas. Why not install an indoor fish pond right in the middle of your living room. Then there would be no limit to the amount of goldfish you could have.
Remember how much fun it was when as a kid you visited your local Koi pond and paid 25 cent for a handful of pellets to feed them. Well now you could hand feed your very own Koi each and every day.
You kids will love you!
