Line breeding guppies

I have been thinking about line breeding guppies for a while now and cant seem to find amy good pure bred strains to begin breeding , any ideas on strains and where to get them ? Thanks

I am currently breeding some guppys , without much suscess, the original adults i brought all died over a period of about 3 months , i have about 30 fry , that are not mature size yet , so am waiting for them to mature to see what happens . Certainly guppys have been so highly breed that they are no longer a hardy fish . If this doesnt work out might try another livebearer

Give Gavin in Newlands garden centre a shout, he used to get the guppies from a breeder up North so he might be able to get what you want
