It's difficult to determine whether the first fish is C. arnoldi. it looks like a female of one of the small species in this complex which spawn at or above the water line.
The second photo seems to show a juvenile Copeina guttata. If so, this will have substantial growth, females to 3" and males to about 4" length. C. guttata are substrate pit spawners and both sexes usually show considerable blue/green color.
