hi shalabin, I would suggest you do more research online on all the aspect on the fish to be able to provide it with a suitable environment and care. Just use Google to search.
One place to start with: http://badmanstropicalfish.com/profiles/profile41.html
I know monsterkeeper forum has a very good writeup all the different Polyterus too.
You can feed Hikari Carnivore Pellet or Tetra Monster Pellet to them. Market Prawn or Silverfish bought from wet market or supermarket can be use too to give them more balanced diet. Your crayfish might become a feeder too, after it just moulted... so please take note!
