Soothing Shrimp

Oh, and if you are figuring out notation for dominant and recessive, often we go capital letter and little letter. Capital for dominant, little for recessive Ie: B r B BB Br r Br rr BB = CBS (25%) Br = CBS het red (50%) rr = CRS (25%)

Following with interest on this thread...

Have a pic? (I love how I can just rattle that off, but when it comes to me- my kids steal my cameras all the time and they're lost more often than found. LOL)

kinda

And rightfully so!

Note they are all saltwater...

Yep. I was going on phenotype to make it easier reading, but perhaps I should have carried it out more. Thanks for elaborating.

Sure. That will help me judge the container. The leaves will be out of the water, and only the roots in- if I do my experiment correctly...

Sure. Go ahead.... heh J/K It would make it so much easier for me to trim the tops of my moss flat. Waves just don't do it for me.

Does anyone know of any L shaped scissors?

PM'ed

So now I'm looking at N.guentheri. Annuals, quick grow and breed. And they don't live for years and years so I don't know what to do with them if I decide to go a different direction. Never tried eggs, and never tried the dry out process, but kinda cool that you can add water and have fish. Go from fry to mature colors in around 5 weeks. Any ideas in what direction to go with selective breeding on these? I know what direction I'm thinking, but always good to hear other people's opinions.

I wonder what they would do with a dead fish.

Pretty soon will be my first time with them. My experiment is going to be placing it on a floating trellis made from styrofoam, and placing it in a covered container with high light.

Thank you for joining and answering out questions. How long have you used it with your stock?

Welcome to the forum hyoushoku. What diy recipe are you using? I know several have asked for making their own remineralizer. I don't know originally what water neos come from. Low ph is not out of the question as we have bastardized a lot of params for shrimp over the years. Most of the neos bought from hobbyists here in the states are bred in 7+ water now and are used to that. When these same neos are put into 6.5 most report that their breeding slows waaaaaay down.

Biofilm is awesome food. However in a pinch you can feed food, and they will eat and be well until biofilm is thick enough for continual feasting. Having said that, I have to agree that 6-8 weeks in a normal circumstance is the best policy

Deta, I agree with you then. Subtle, I have no doubt some foods can enhance coloration. But, as Taylor here said- color may be enhanced, but it won't change genetics.

I have algae free moss in my fish tanks. I think it's java. They have ramshorns in them, but no hair algae.

I'm really liking the N.guentheri

I've seen that for bettas.

...but they molt as they get older/bigger, and that's when they naturally start coloring up anyway...not sure how you could tell if the food was doing anything unless you had two tanks of the same strain side by side...

I'm proof of that...and pizza!

Great job! I hope it is okay to expound a bit further on your article. The common accepted theory is that the black is dominant over the red in CRS. This is if we are dealing with homozygous backgrounds. Homozygous means having identical pairs of genes for enough breedings. You know that there is almost no chance of that particular shrimp throwing anything else but a phenotype (lookalike) of itself. Creating a homozygous recessive (CRS) in theory is pretty easy- since the recessive is lowest on the totem pole, no other color should pop up. HOWEVER, there are always surprises in backgrounds. That is why breeders often do test breedings. (Ie. Testing a "Pure" red strain by crossing with a golden to see if any goldens are thrown. If so, it has golden in the background close enough that it is not really Pure.)...or breed lines for several generations to make sure there are no "surprises" in the background. So assuming the crossings are from "Pure" homozygous shrimp: CBS x CRS = CBS The CRS is now hidden in the background of the CBS offspring. This is called heterozygous. Or het for short. The pheonotype, however, is CBS. As mentioned above in the article: CBS (het CRS) x CBS (het CRS) = CBS + % CRS --- TB, unfortunately, we really don't know too much about. If there were just two colors, perhaps it would be more black and white. (Pun intended.) But there's a lot more than that. Often the punnet squares just don't work on TB. Why? Well, there's also the real life challenge of hierarchy of genes and recessive genes. For example, let's say green was an actual color for crystals. The hierarchy may look like Green > Black > Red Black x Red = Black Black x Green = Green Red x Red = Red Green x Red = Green Now all these genes are involved and can throw Black, Red, or Green. Trying to separate these out can be quite confusing with all the shrimp having different combinations of backgrounds and throwing different types... and this is just an example of 3 types of genes involved!...and just simple dominances and recessives! I'm sure part two by 00camadro16 will discuss co-dominance and modifiers, which can be more confusing yet and applies often to TiBs and Neos as well as TBs! Bravo on a job well done!

IMO Shrimp + Assassins + very little food = Assassins. They are meat eaters.
