This strikingly-coloured bladderwort hasn't been identified any closer, and there is not much information about it. Nowadays it is probably not cultivated in Europe, and not available in trade either. It is possible that aquarists in Asia still have it in their tanks. Details on cultivation, demands and habit vary.
