I have see some fish that has no colors or it's not that special making it to the top 10 ????? No offense But why is that ????? I just don't get it , some cool and colorful fish that i have didn't even have a rank !!! Why is that ??

Sometimes it is because the fish does not have that many votes and I am assuming the person who posted it gave it a 10. It is easy to screw with the system when a picture is just posted because the pic appear so much that people can easily find it. However, usually these will steadily fall down the line as more votes accumulate. Once you reach 100 votes, the voting really slows down and it is almost impossible to skew it in your favor.

Yea but my tank and fish are better than urs lol

I don't know how to categorize my tank actually, It's a cichlid tank but has live plants, but has sand.... So I put one in planted and one in non-planted.
