Dark/bronze goldfish, the original color before humans bred them to be orange.

a carp then? these fish came from a nearby wild pond as eggs or fry

It means your fish had a baby and it didn't come out orange.

there were two dark fish in the pond before i ever put goldfish in the pond. they came from a wild pond.

Not a carp; goldfish.

Looks like a specie Carassius auratus only Black which is quite common.

one thing that is confusing me regarding the goldfish id is that the body shape. it appears that the body narrows abruptly before the tail as opposed to a gradual taper, especially from the belly area. hard to see in the vid.

Wild type Goldfish

Fancy' type Goldfish

i think its crucian Carassius carassius as i see rounded fins u can decide after reading these parameters since its not clear in video , can b hybrid with others and its the smallest of all . The difference between Carassius auratus and crucian Carassius carassius is ... Carassius auratus & Carassius gibelio ie goldfish has convex fins while crucian has convexly rounded fin .

The crucian is a medium-sized cyprinid, typically 15 cm in body length, and rarely exceeds in weight over 3.0 kilograms.[4] But a maximum total length of 64.0 cm is reported for a male,[5]and the heaviest published weighed 3 kilograms.[6]

They are broadly described as having a body of "golden-green shining color",[7] but a more precise source states that young fish are golden-bronze[8] but darken with maturity,[8] until they gain a dark green back, deep bronze upper flanks, and gold on the lower flanks and belly,[8] and reddish[citation needed] or orange[9] fins,[10] although other colour variations exist. One distinguishing characteristic is a convexly rounded fin, as opposed to goldfish (or C. gibelio) hybrids which have concave fins.[9][11]

----

Goldfish were bred from Prussian carp (Carassius auratus gibelio) in China, and they remain the closest wild relative of the goldfish. Previously, some sources claimed the Crucian carp (Carassius carassius) as the wild version of the goldfish.

However, They are differentiated by several characteristics. C. auratus have a more pointed snout while the snout of a C. carassius is well rounded. C. gibelio often has a grey/greenish color, while crucian carps are always golden bronze. Juvenile crucian carp have a black spot on the base of the tail which disappears with age. In C. auratus this tail spot is never present. C. auratus have fewer than 31 scales along the lateral line while crucian carp have 33 scales or more.

When found in nature, goldfish are olive green. Introduction of goldfish into the wild can cause problems for native species. Goldfish can hybridize with certain other species of carp. Within three breeding generations, the vast majority of the goldfish spawn revert to their natural olive color. The mutation that gave rise to the domestic goldfish is also known from other cyprinid species, such as common carp and tench. Koi may also interbreed with the goldfish to produce a sterile hybrid fish.

is it really as unusual at it may seem to wind up with wild goldfish with all the fish it might have been?

After viewing the video, you may have both Crucian and Gibelio carp.
