sera Pleco Chips is the staple food without dyes and preservatives for rasping and suckermouth bottom fish such as Ancistrus and plecos. The balanced composition with a high amount of fibers (from willow bark fibers and alder cones, among others) as well as natural spirulina supports healthy digestion and development. The quickly sinking chips become smooth in water, keep their shape for at least 24 hours, and do not pollute the water. They therefore allow the mainly nocturnal catfish eating slowly without any problems, which meets their natural feeding habits.recommended feeding sera Pleco Chips:Feed sparingly once or twice a day, night-active catfish prefer to feed in the evening.Ingredientsfish meal, corn starch, wheat flour, wheat germ, spirulina (4%), brewers yeast, milk powder, fish oil (containing 49% omega fatty acids), herbs, whole egg powder, willow bark, alder cones, stinging nettle, alfalfa, mannan oligosaccharides, parsley, sea algae, paprika, spinach, green-lipped mussel,
