They are fine for pets and to sell/give to pet stores :)
The only things different now are the different fin varieties, and even new pectoral fin varieties. Keep in mind you don't want to mix the fins unless you have a goal and know how to achieve it when mixing. So you did right by getting a CTxCT (I see too many CtxVTs and people don't realize the flaw it will create :( )
I say if you like them, then breed them at least once to get back into the hang of it.. see what you get from them. May not be the best, but you can sell the juvies off to people for $5-10 each, and sell/give to a local pet store the ones you don't sell :) It will be the coloring (like mentioned above) that will grab people's attention. The black of them is liked by many.
