Is this Rd anything special?

That doesn't make any sense at all. Being captive or not doesn't have anything to do with their genetic makeup, barred parents will throw barred offspring continually almost 100% of the time. If you kept crossing barred fish you'd end up with a F342342 that was still barred.

Being barred or not doesn't tell anything about how closely related the fish is to the wild at all.

Being captive obviously DOES have a lot to do with whether or not they are barred.

Barred parents will throw barred fry, but they will also throw colored fry. When you breed their fry's with their fry's you're going to end up with even less barred fish. It's a ongoing process until you end up with 0 barred fry a few generations down the road. I don't see what's so hard to see.

Do you understand the f0, f1, f2 thing? It's not different batches of fry, it's different generations of fish.

mine looked like that till about 4 in, i think its a barred

We're delving off topic here...

I fully understand the bastardization of Filial generations used in fishkeeping to denote generations removed from the wild.

I'm not sure how else to explain it but your assumptions on genetics and breeding are incorrect.

Wild barred fish have homozygous alleles for color (lets represent that with AA for now). Two barred fish produce fry, all fry have to be AA as well (using the classic Punnet square). Cross these and you still get AA and so on...this doesn't account for random mutation which can cause barred to throw the occasional colored individual.

Under your assumption all barred fish would be gone from the wild in a few generations because after a couple generations there would only be colored fish produced...

There are scientific studies done on the subject, but my access to them has expired.

Nice pick up! Can i ask how much you paid for it?

it was $25 au i didnt mind paying so much for him because i liked him.
Im really hoping he does turn out to be barred. thanks guys.

So you're saying that every time barred midas breed and colored fry are produced those are "random mutations?"

I don't think you can call fry "random mutations" when they consistently turn out this way. From all the people I have known who bred f0 and f1 barred midas their fry have usually turned out about 50/50 but a lot of the barred fry's would peel into colored fish.

The fish all carry the same genetics, some are colored and some are not. Just because they have the identical genetics doesn't mean they're all going to look the same. I don't have the same color hair as my brother, does that mean he's a "genetic mutation"?

I will admit that I do not know why they are barred in the wild and colored in the tank, my guess is something with UVB but I'm not a scientist. It's just the way I know it happens. People pull barred fish from the wild every day, take them home, and days/weeks/months later they are colored.

If you had two barred that were heterozygous (Aa) you could end up with 75% barred and 25% colored if the gene for barred is dominant. (I'm not sure if it is or not).

I can understand that. I wouldn't know where to start looking for a 100% genetically barred fish though.

duno,,,but its such a cutie! x

my brother has bred two barred midas and have gotten all white midas and colored midas from the spawn just thought i'd mention that not here to debate but have kept midas for over 17 years all midas complex.
