We're planning a guide to our readers' top 100 fish for the Christmas issue of Practical Fishkeeping.
To help us compile the list we'd like you - the readers - to choose your favourite three and let us know why you've chosen them.
Once the votes are in, we'll compile the top 100 and in publish them in the Christmas issue, along with a species profile for each one.
You'll also get the chance to see what other readers, PFK contributors and the PFK team ranked as their top three, and why they chose them.
You can vote for your favourite three fish here
