Your site looks good, although I can see it's not finished. You're missing anything for marine and DIY, and there's nothing in the Fish Diseases section.
I think you should keep working on it. Try making your information more thorough; instead of just mentioning something, make sure you go over all aspects of that topic, especially if your site is meant to help people. You want to give the best information you can give. Keep building onto what you have. For instance, there are tons of fish and plants that you have yet to add in your information sections. Also, try to work on the way you word your sentences.
