This is a plant I’ve tried importing half a dozen times, and never had much success with. Even though leaves fall off in transit, an intact stem is enough to grow Gobenias back if conditions are good. There are many ‘clones’ of tropaeolifolia, some of which could be different species, but it is hard to know for sure. The nicest colony of this species I’ve ever seen was at an orchid growers greenhouse, and it sat, neglected, on a giant piece of lava rock. There were hundreds of perfectly formed leaves and not a sign of melting. I’ve tried growing this species on sphagnum and clay/leaf mixture (below) but they have not done well. Recently though, I have seen some growth after adding a small vent and am hopeful that with better ventilation it will recuperate.
