beginner freshwater planted aquarium
I'm new to the hobby, but I would think that this is too small for most fish. I recently had to buy a second small 5 gallon tank with built in lights , thermometer and filter. It's now my hospital tank / quarantine tank. You can find them at most stores, I live in China and in USD it set me back.....(converting)...$30. I had a spare heating rod and air stone but I'd recommend them. I'm not sure which fish are native to washington but I'd recommend Betta from my limited experience. They have so much character and would be comfortable in a 5G with some plants / deco. My betta follows my finger when i dip it in, and even rubs against it like my cats do.
