Crab Loops is the staple food without dyes and preservatives for all crabs in fresh and marine water. The balanced composition with ingredients close to nature, such as spirulina and willow bark provides everything the crabs require for healthy growth and safe molting. Fertility, splendid coloration and disease resistance are enhanced in a directed way. The sinking loops retain their shape for a very long time, thus allowing the crabs – according to their natural feeding habits – to easily grab them, carry them away and eat them in a hiding place, without polluting the water.
