I think these sorts of fish things are eminently suitable for placement on the top of the loo cistern - watery theme and the right size - (as long as your loo doesn't do what ours does - something goes wonky in it's gubbins after the flush and it moans and it groans and it sighs and the entire loo vibrates.... my fish started wandering about!).
I thought some of these fishy things have recently been attributed to Nazeing?
(mine's an unusual one too, but it's got it's label on, made by Sticlart. Quite contemporary, a TKMaxx special. :thup:)
