How much would these pets be worth?

Erigone the Ginger Valabex              Clytaemnestra the Cream Valabex

 Antilochus the sepia Valabex

I'm not sure which of these pets I'm going to sell, or even if I'm going to sell them at all (I like thier names and thier colors, especially Erigone) I'm just curious as to how much I could get from them

It really depends on who is buying and how much they like the names. To find the base price of a pet, just use the search pets area, selecting to order by price.

 Most people on res value pets for names though.
