The fish tanks (not the fish) are breeding

Although the purpose of breeding the tanks is so that the fish will breed :)

The other week I inherited Vic's old tank, last week I borrowed a light and a filter off Daniel and Fee, and today I got an air pump and hose. So now I'm all set to put the tank together and put some fish in it. Before I put my angels in, I want to test that the piece of fake slate I have is fish-friendly. It's not aquarium slate, it's actually an offcut of a roof tile from my friends who just had their roof redone. So will need to test it out with some canary fish for a few weeks before I let the angels near it.
