Advertisement opportunity

For those who want to advertise on aqua-fish.net directly, I created ads.aqua-fish.net. It is not link selling since I don't want to face potential penalty in search engines. Instead, it's a type of advertisement which allows one to sell products effectively. For example, if you want to sell a book about Discus fish, you can pick only pages about Discus fish. In return you pay less and conversion is more likely than a sitewide link somewhere at the bottom of pages.

There are also some discounts available:). So if you have something to sell (related to fish and aquariums), consider this offer.
