I'm trying to learn about the genetics now... I know genetics, just not what the names relate to. Is it Taiwan Bees that throw off all kinds?? Blue Bolts, BKK's, etc? I've never had luck with cardinia. I've always used tap though. Are you using reconstituted RO? How much of whatever booster are you using? I've got a buddy that may hook me up with some Taiwan Bees. I want to try with them before I try with the OEBT's that I've failed with three times...
When I started in this hobby about 10 years ago, we only had like 10 variations of shrimp. Fire Reds and all of the different grades including Red Rili (I'm counting that as 1 color). Fire Yellows. Tangerine Tigers. OEBT. Wild Tigers. Crystal Reds and Crystal Blacks. Blue Bolts and Snow Whites. I got back in to this hobby this year and was blown away to see multiple shades of blue, green, pintos, galaxy pintos, wine reds, red bolts, fishbone patterns, etc. So I was dying to get a Taiwan Bee tank started in order to try breeding BKK's, Wine Reds, and Blue bolts. So far my wine reds, pintos, BKK's, and blue bolts are all breeding interchangeably. From all of my research, these different Taiwan Bees will produce any variation of themselves if crossed with one another. In other words.. BKK's and Wine Reds both carry the black gene. If bred together, I should be able to get some BKK's, some wine reds, possibly an RKK. It all depends on which genes are dominant or recessive in both parents. If you are really interested in researching genetics, purchase the Dennerle magazine called "Breeders and Keepers" SECOND EDITION. They go in to great detail about genetics and have scientific graphs and diagrams to help people understand it. I bought mine for $20 on amazon.
In terms of water, I never use tap for Taiwan Bees. When I was in to breeding years ago I used RO for my Neocaridina colonies. I didn't have the right soil to buffer though, and could never get CRS's to breed. I would see a baby here and there and they'd all die off and then the adults would disappear over time. They need RO water that is remineralized. I use Salty Shrimp GH+ and it works perfectly to remineralize the water. I just followed the guidelines on the bottle.
Best advice... If you want to do Taiwan Bees, do it right and it will save you time, money, and headache when you lose most of a colony. This is why I started this thread so people could see what Taiwan Bees need.
ADA Amazonia soil is a must.
Salty Shrimp GH+
C02 injected at 4bps
pH - 6.2-6.6 (achieved by using ADA Amazonia. Others like Fluval Shrimp stratum don't do this for you)
TDS - 159-180
GH - 5
KH - 0
I hope that helps. I've got about 8 berried Wine Red mommas right now. I'm dying to see the first babies. Will post photos once I see some.
