MYSTERY FISH QUIZ #7

Hello Folks!

It's time to go underwater and explore the wonderful world of UK fish. Some are spotty, some have stripes. Some prefer lakes, others prefer streams. Prepare to get your feet wet and get your fins in a flap!

Each Monday for 12 weeks I will be posting a little teaser for you. Without looking in books or on the internet (i.e - no cheating), see if you can identify the UK fish On Wednesday, so as long as no-one has guessed it, I will post one clue. On Friday I will post the answer along with some additional information for your interest.
