The particularly lightweight net is especially non-irritating to the sensitive mucous membranes of fish, making it ideal for extracting even the most sensitive types of shrimp and crabs from the aquarium. Its black color greatly facilitates the process of catching aquarium inhabitants. Many animals do not perceive the black color perfectly. By holding the net tightly, some fish may mistake it for a refuge they can hide in. Is there anything easier than that? The specially rounded corners ensure an optimal catching process.
