Yeah BettySplendens never renewed her site, basically she stopped paying for it so it's not working any more
I wish I had saved all the info on word docs or something.
With DT/CT cross you'd get a whole range of things including regular DT's and CT's and some DTCT mixes. You'd get varying web reduction but with careful breeding you could reduce the webbing to make a more proper DTCT, it will take a few generations and careful preceeding but it can happen! Chard66 is currently working on some DTCT's and had a few up on aquabid a while ago.
As for red a 'silver', that would be Copper so depending on your males color I would try to find a copper CT female with very good web reduction and even reduction all around the fins. Like this girl here
EDIT: found one of chard's DTCT's http://www.aquabid.com/cgi-bin/aucti...sdt&1390519204
notice how the ray's seem small, still lots of membrane between the rays so eventually over a few generations you want to keep trying to reduce it to make it look more like a CT with two lobes for the tail.
