I have been to loads of fish shops in search of live food for my breeding of betta splendens, but it seemed that they only stocked them on a very random basis.I replaced live food with boiled earthworm cut up very finely (it works great), but i went to all the hassle of finding or digging them up , scalding them with water , cutting them with a scissors and freezing them for later.... and being always told by my fiancee that I was disgusting. One day my 6 year old daughter returned from a toy shop down the road with "sea monkeys"? I never heard of them either, on close inspection they turned out to be brine shrimp that a child could harvest and keep them for a guaranteed 2 years, they multiply or breed or whatever readily.....I couldnt believe it, happy days, so its the toy shop for pet food and pet shop for pet toys ( i have dogs too).
