Oops, I just realized I missed a post a while back. I guess Italybass already felt he had identified the minnow and therefore when he stocked some more in his pond he used their specific name. I, not realizing he had done this, was working backwards from the name to see how well they matched the pictures online and in his post. It appears you get to the same answer no matter which way you do it

and... I learned it is an invasive species!
-------------------------------
Invasive species
The fish was introduced in the 1960s into ponds in Nucet, D�mboviţa County, Romania and it made its way into Danube, then spreading throughout Europe. They pose danger to other species such as the sunbleaks (Leucaspius delineatus). They are the carrier of a parasite (Sphaerothecum destruens) that is not damaging to the topmouth gudgeon, but attacks other fishes like the sunbleaks, which are unable to spawn and have a higher mortality when infected. They also feed on eggs of locally valuable native fish species.
The species has also been recently discovered in several lakes in the UK where it is believed to have been illegally stocked.This has called for a large scale eradication program organised by the Environment Agency who kill the fish off with a piscicide called rotenone.

Either way, glad you know what they are and that they are good forage for your LMB!
