Me too, but I can think of worse places to be than where you are... I love growing crypts.To bad you're in the UK. I have some really nice red crypts in need of a home.
Polypterus are fashionable right now, and are being heavily imported. A few years ago, they were hard to sell, but tastes change. The question is how many of the people who want to buy these "dragons" realize their eventual size and their needs in fishtanks. I see them becoming the next big "my bichir has outgrown my tank does anybody want it?" fish.
Cue that for about a year from now.
A lot of new aquarists are buying very young ones and I'm not sure how many are doing what @Jennet is sensibly doing, and looking them up.
