Hey Slief,
Great pics! Really brings back memories.
In pic 1-2 the fish is called "aal" or "paling".
They really are good smoked "gerookte aal", but I wouldn't eat them out of the canal /gracht.
Not sure if I should link this, but it's kind of funny espec. if you can understand what they are saying.

Keep sending those pics, but pics of the "acquarium fish on the Walletjes is not a good idea.
You're lucky you didn't end swimming with the fish in the canal.
