Your fish won’t live for super long but a cooler and a portable bubbler keeps them going for maybe a day depending on how many there areYup. I’ve tended to stay away from it just because I like the idea of being mobile if needed. It’s not hard to bring a cooler of live fish or six hens and a roo somewhere with me if relocating is necessary. Bringing a hydro/aquaponic system with me might be a stretch.
