WANTED: Light

Hi, I teach in a small SEMH / behaviour school in the West Midlands. I’d really like to have a cold water fish tank for the students to enjoy and learn to understand cold water ecosystems. I have a tank, I’m just looking for any one that may be willing to donate the additional items I need, cold water plants, rocks, woo, gravel or a light and filter. If anyone can help it would be greatly appreciated. Please message me. Thank you
