Sera Spirulina Tabs are an ideal food for livebearing toothcarps, East African cichlids and other algae eaters. Suckermouth catfish such as Ancistrus also love this food. Due to over 25% Spirulina, the tablets contain a high amount of color enhancing carotinoids as well as particularly easily digestible protein. The tablet is pressed to the inside of the aquarium glass for directed and controlled feeding at the front pane.
