Oh, I’m sorry – it’s my mistake. German and English beautifully mixed …… at least in my head.
Yes, Bambus in German is bamboo in English. The hollow canes make good caves for many fishes – my Pseudosphromenus like it, and some Badis (e.g, singenensis) species, too.
The bamboo has to be completely dry. If you cut it just behind the leaf nodes, you get a cave which is closed at one end. Before putting it into the tank, you have to water it until it sinks – or rather a bit longer.
