Tubifex e nematodi - Shrimps passion

Si possono incontrare dei vermi sottili e filiformi di colore bianco che si muovono liberamente per la vasca, i nematodi (Fig.1 e un video dov'è possibile osservarne uno in movimento "nematoda in aquarium"), o altri molto simili ma molto più lunghi, dal colore un po' più rosato e che rimangono ancorati al substrato, i tubifex, famosi per essere allevati e utilizzati come fonte proteica per i pesci (Fig.2 e questo video "tubifex worms in aquarium").
