Cull from a red rili line


Kelly

Recommended Posts

Ok I bought a cull from a guy that breeds red rili. I didn’t want to buy top quality shrimp yet because I’m new to shrimp hobby and bound to and have (bought a internal filter tank my 1st mistake) make mistakes. I have been researching the subject but as you all know there’s a lot of information out there. Now I think the females I have has  recessive rili gene in them  but they are all red bodies and don’t show rili markings at all. I am guessing they fire reds....but unsure. The males I think are low grade rili. Red head and red tail somewhat clear middle. What’s my chances of getting a good rili out of this batch? Do they get their looks more from their mothers or dads? If they have shrimplets I plan to cull them by putting unwanted ones down stairs in community tank. When I feel ready to buy a good batch of rili should I just put all  these ones down stairs and  focus on the good quality shrimp or do it the hard way  and breed all and see what I end up with?

It's difficult to tell. You should ask the person you bought them from what he thinks it is.

I wouldn't call them Fire Reds, as that will confuse the situation. Rillis do not revert to Fire Reds.  And an almost red Rillis does not make it a Fire Red.

If the guys says these are Rillis, than what you have are just Rillis, albeit low quality Rillis.

Yes, separate them. Breeding these current low quality Rillis with a better quality Rillis will just produce poorer quality overall. 

Say you buy new A grade shrimp and breed them with C grade shrimp. You end up with shrimp between B and C grade, never A grade.

Offspring will get traits from both parents.

I mean, the shrimp you have there is already a beautiful shrimp. If you want to turn that line into a rili line, using the low grade rili males, it'll take a few generations to get some nice ones popping out, and at that stage you'll probably want to bring in someone else's rili line anyway to increase genetic variation. It's up to you whether you want to go for the more interesting alternative of breeding your own line, or just buying one. Just know you're not likely to get anything special from the first batch.

The shrimp in the picture looks more like my bloody mary than a fire red.That is a female with eggs inside........ lovely solid colour!

I wouldn't get too bogged down with what to do in the future at this stage, wait and see how it goes with the current batch, removing any poor quality as you plan. There is no real way of knowing what shrimp carries what genes when you start out as you are?

I know they aren’t cherry...they too red and I don’t think they are Bloody Mary their flesh aren’t red and I believe Bloody Mary has  red shell and flesh. They do have red legs though...

I know I have a  berried  shrimp... one came that way but I just noticed another molted..... so maybe more on the way....I still want to move them to 8 gallon eventually...but I’m unsure when the little shrimplets be born.....

Why would you say that? It's certainly not a Rilli. Looks more like a Red Cherry to me.

Definitely looks like a high grade cherry to me. And as with Simon, I'm leaning towards Bloody Mary.

I meant low graded cherry. They too red in colour. They probably have  low grade cherry in their background and I’m sure if I don’t cull it will eventually show that. The breeder is working with red rili line. This is a cull from that line. 

I will put them in the 8 gallon by this weekend I think. I want to make sure everything ok 1st.

      If that is the offspring, then the parents are unlikely to be PRL. I tend to agree with you. There are very few PRLs in Australia. And any that claim to be needs to show proof. PRL genes have to start as PRL. CRS that breed true after x generations doesn't turn it into a PRL. Neither can a Taiwan bee shrimp turn into a PRL despite how ever many generations. I've never seen a PRL with that sort of red colour. I have on Red Wines and Red Shadows - Taiwan bee shrimps. So somewhere down the line one of your shrimp might have been mixed with Taiwan bees and is no longer PRL. It just tanks one shrimp to mess up the genes of a whole colony.

      Sorry, missed this one somehow! The PRL look fantastic and the odd ones look part PRL and part Red wine/Red shadow in the colour. They are still very beautiful but ideally should be seperated to help keep the PRL clean if you can do that.  Nice clear photos!

      Hi SKF!   So I bought some PRL (or at least they were sold as such. These claims are dubious in Australia as people don't know much about the genetics, nor do they care as long as they can make a quick buck). After 8 generations of breeding true, I'm having around 1 in 200 throw a much darker red. They almost look like Red Shadows, but I don't know too much about those types of hybrid. Can anyone help with ID'ing the gene?   TIA (First 2 pics are the weird throws, second photo is their siblings and the last photo is the parents)

      Thanks for taking the time to do the update and photo. Very pleased to hear it is now going so well. Different plants have different requirements so you need to check they will thrive/survive with the setup, light requirement/co2 etc or just get more of what you have, there are various Anubias if you want some variety. The number of shrimp shouldn't affect what plants do well! Maybe just get one plant at 6 month intervals and have another go, things change in time and you don't need many in a small tank, and the ones you already have will grow over time as well. Good to hear you got rid of the scuds, I did the same, manual removal when I had them, but I caught it quite quickly and only had substrate in the tank!

      Maybe it’s time to give some feedback. I forgot the time I could see only 2 shrimps, since then the population has grown so much that I gave 30 of them a couple of months ago. Then again now I think the population went over 120 and I am giving again about 70 of them. Not sure why they died in the beginning, maybe they were quite old. They were fairly big! Or it was the planaria? I got rid of them and scuds. The second one was not easy. It was out of control so I emptied all the shrimp population from the tank and poured sparkling water for a couple of hours. Some scuds survived that! But eventually they disappeared in some weeks after manual removal each time I could see one. My only problem is that plants dont go well anymore.  xmass moss, dwarf hair grass and anubia nana go very well but other plants progressively died. (Not suddenly) - Is it due to shrimp over population? - the sparkling water treatment ?  - i can’t see other issue, i provide generous lighting, co, fertilizer (in soil and in water). I have a bit of algae but under control.
