Name that fish!?

Can anyone help me with this?
Is this a goldfish of some sort or is it something else that somehow came in from the creek?
There are at least 30 of these in the water garden (this is the largest so far) and they ate up the hornwort I put in!
Had to resort to putting the hornwort in the bio-filter and in a big mesh laundry bag in the water garden--lovely to behold.
Anyhow, should I cull some of these and 'Freecycle' them?
I'll post a picture of a smaller one with what I know must be a goldfish of some kind.
As always, thanks for your suggestions,
Teresa

And here's a photograph of a smaller one with what must be a goldfish.
I know nothing about fish, so any advice or information would be much appreciated!

Last of my fish pictures--here you can see them both in 'profile', but the orange one obscures the tail of the silver one--makes it hard to compare!
Those are little juniper/cypress berries on the net with them.
(No more fish pictures today. I promise.)

They are both goldfish. The dark colored one just has not gotten it's final color yet. I takes a while for them to turn gold most of the time. The dark color may help them to avoid predators until they are old enough to learn how to do it and to get large enough not to make an easy meal for other goldfish.

Goldfish. They reproduce faster than rabbits. The color is not unusual. Most of them change to another color(s) in one or two months or some may wait as long as next season. A few won't change at all. I have to repeatedly cull. I culled to 5 from 20 in one small pond early spring. Last time I cleaned the filter in that pond I counted roughly one dozen 1-1/2" 'rs same color as yours. Sigh.

That is a gold fish Teresa. I have had gold fish for the last 27 years, I have some like that, They are this color and may turn colors or may just stay this way.Fish genetics are funny. The color they turn out to be may come from fish several years or even decades ago. There is nothing different but the color. It is all in the genes. Bev

Thank you all very much!

I had read that goldfish are more darkly colored when they are small, but not having 'raised' any myself didn't know what 'small' meant, especially when there were a few similarly-sized fish that were 'gold'!

Thanks again,
Teresa

I have one gold fish that didn't start to turn its color until it's over 4" in size. The last few weeks it has been fun for me to watcj it transforms from grayish black to gold. This evening I was stunned. The little thing is almost solidly orange, with black strip on its upper body. Oh yes, and I've some babies too as a bonus. Our pond is a little over 1 year old. :-)

Hang on to your lovelies, mine have become Heron food. Now furiously netting and stringing the ponds. I'd like to have some goldfish left, of any color! These ponds are located one on the street side of a front yard and the second in the back yard. Herons seem very adaptable to the suburban neighborhood environment.

Snaple; likes this one? LOL, we've plenty of them here to share....(just kidding).

I don't know Lily. snaple might be able to throw a rock that far. She has been practicing ya know. LOL

randbponder; I need to get this Heron I.D. One morning I woke up to the sight of it having breakfast on my pier. (thanks goodness it wasn't one of my Kois/gold fish). But let me tell you the fish was almost as big has its head (the Heron). How is that possible? If you notice; it has a shorter neck than the great blue heron, or the White Heron that are common seen around our Lake.

I'm practicing with a canon! Some parts of Mother Nature I intend to interrupt.

Lily_love, his neck will look considerable longer in flight, But I do agree. That one looks like the ones we get around here. and not quite as big as most.
I will say they don't like netting. My pond isn't shallow enough for them to wade. I do have a small preform that between them and raccoons. that did get cleaned out. I have plans to build a gazebo or some kind of shelter over that one. Just don't know when I will get the time. until then I just use it for plants.
Good luck, on disturbing it's haunt, enough to keep him away.

Snapple, you need a spud gun! It's a pressurized tube, that shoots potatoes.....what a hoot! Most it can do is thunk a neighbor if they get too close....but hey, what's a good thunking between friends...eh? ;)
