Haha good old Clacton-on-sea!
I have not kept a Jardini, but done tons of research after interest.
They are totally solo fish, very few will tolerate tank mates.
So unless you got a tank to offer just to him in the likely case, i would give him a pass.
Very good price though i recon!
Ha i just remembered Dan is from Essex as well (the MFK monster supplier). So that makes 5 of us, i definably recon us Essex chaps got a thing for the tank busters apposed to your bread and butter fish.
Ah on the note of bread and butter fish, have you been to Wet Pets in Romford by any chance?
