I have a question about the nets commonly used aquaria. They all same to be made of nylon or something similar and for years fishing nets were the same. But reletively recently it's come I light that nylon removes the slime coat of fish welcoming them to diseases and parasites. No where is this more evident then trout fishing where they began using rubber nets to do less damage to the slime coat. My question is does anyone know of an aquarium net made of rubber netting and if not is this something that anyone would care about spending a little more money on to better protect their fish?
