i got mine from nantwich , stapley water gardens, its about 15 miles from where i live, but i've been in a couple of times since and have'nt seen any more, i'd try to ask your local fish store if they could order you one, yes there safe with neons, i paid i think £8.99 for mine , had him now for around 12 monthes, if you can get one they are worth it,
