Black Ram fry.. thanks Brian!

[brewmaster15]

Awhile back Brian (Jeep) sent me a bunch of Rams.. Blacks and Golds. Most are in a group still but I set up 2 pairs of Blacks and though I got eggs ans some fry..nothing great and the pairs ate them. One of the tanks is on my desk... I have been so busy with Discus I honestly gave up trying to breed these ..figured I will just leave them be. The tanks not really set up for fry... guess they didnt get the memo.

The other pair also didnt get the memo and is sitting on eggs in their tank.


Thanks Again Brian!

That's a pretty decent group. I'll tell you a little secret that I stumbled upon not long ago...If you cross a gold with a black that has been bred black to black for several generations, you'll get a noticeably higher percentage of blacks.

Thanks Liz I will have to try that one since Brian sent me a good number of Golds too.

I had given up on mine as well but they didn't get the memo either, and when Rams spawn they're serious about it. I had two spawns of Rams and two spawns of discus happening at the same time and all the sudden every ounce of tank space was filled. I've seen several spawns form the offspring recently but they're in community tanks so no success. I'd like to have more of them because they're in pretty high demand in my area, but I don't have the tank space.

I'm glad they're working our for you!!

Ok so question here for Liz,Brian, and Chuck...or any one else that knows this...

Brian sent me gold rams too. If you breed black to black you get black rams and gold rams. IF I breed gold to gold from those do they throw just gold or. Does gold x gold here throw blacks as well?

[LizStreithorst]

I never tried it because the most obvious answer is that they would all be gold.

[Charlyc11]

I did not breed gold x gold either but I think Tom did and got all gold. Correct me if I am wrong Tom. I only bread the Blacks and got 50 % Black max.

Lol..so black x black the obvious answer is half black and half gold.. but. Gold xgold the obvious answer is all gold? Hmm.

Obviously

Thats the ratio I saw too.


Now then what about gold x black.? What ratio of black to gold?

[LizStreithorst]

I've made that cross of colors several times. I always saw larger percentages of Blacks by crossing colors than when breeding Black to black.

Thats interesting Liz.. Im not sure what it means genetics wise but thank you.

I new Liz had the answer but I did not want to put words into her mouth.

From what you describe in these two color forms of rams it sounds like gold (xanthic/yellow) is recessive to black, as it is in most fish species.

But if that was the case.... Black x gold would give all black as a phenotype...

Not necessarily. If the black is heterozygous and carries the recessive gold gene, black x gold would produce as much as 50% gold depending on the pedigree of the black. Only if the black was homozygous for black and not carrying the recessive gold gene would it produce only black fry. Conversely, gold x gold can only produce gold because the dominant allele, black, is absent.
