Ok so I'm thinking about building a pond in my room, something small for some goldfish or something. I live in an apartment with my family (I'm only 14) but I'm quite experienced in fish keeping.
So there is a small bathroom in my room with a shower I never used (and never find use for it) and we even took the shower curtain down. Now all it is is just an empty space with a short wall around to keep the water from spilling out (when it was used for a shower)
So I'm thinking about using the small shower wall as a pond and full it with water. Here's a Birdseye picture to show you what it looks like
Me and my dad figured out what to do with the drain. We plan on putting a cup over it and then ceiling it with silicone.
The wall is about 6-7 inches tall and my dad estimates it holds about 15 gallons. I'm thinking about using an undergravel filter (since no other one quite fits this design) and an oxygen pump in the sides of the pond. We'd just use beneficial bacteria from one of my other fish tanks to instantly cycle the tank, then all I need are some Lilly pads and goldfish!
My parents are fine with the idea but our apartment is a rental so the only rule is that the silicone that I apply to the cup over the drain must COME OFF once we move out (which won't be for many years)
Would this potentially work? Where could I find pond decor like lilly pads? Is anyone familiar with live plants? I have a 1 gallon filtered tank that's currently unoccupied so I can practice keeping some live plants in there. What would I need?
