Trouble with grading shrimp morphs

Recommended Posts

Baccus

This may be a really stupid question but I have been having a great deal of trouble deciphering the actual colour quality (depth of colour, clarity or thickness e.g semi see through or solid) of the different named cherry shrimp morphs. I have looked online and here and pretty much get the mat coloured graph which doesn't really go into the actual grading process. Is there such a definitive description with live pictures to go with the shrimp, or is it just everyones best guess? I did stumble across one lot of good colour photographs of some of the grades and morphs but it only had reds and even then no mention of bloody mary.

I guess I'm looking for something like all other breeders of show species follow. For example Certain dog breeds if shown can not have odd coloured eyes or only be set colours not liver or brindle or must have a black tongue while conforming to the rest of the show standards such as size, coat type and tail length.

What for example distinguishes a Fire Red from a bloody mary? Is it only the line breeding that they followed to get to the colour or is there something else I am missing? Or a blue dream from a blue diamond or just a blue cherry?

Usually I am happy to just have what I consider nice coloured shrimp, but when people go to buy them they want a name, and aside from doing the easy thing and giving my shrimp any old name that fits, I would like to be able to actually give a named colour morph with perhaps grade A. Mid or Low.

Bloody mary are not a grade of shrimp, but a color, just like blue dreams and chocolates. They may have their *OWN* color grading, but I haven't seen much in regards to a specific grading for them. That said, a high grade bloody mary is likely to have solid red legs and dark coloration.

FR/PRF are opaque shrimp that you can't see through. BM glow like a ruby and it can be difficult to get their true colors to appear in pictures. It's easiest to appreciate them in person.

There is no "blue" cherries, but there are many blue varieties... and trying to define the blues is a headache.... for example, Blue Velvet in the USA are supposed to be Blue Bodied Red Rili's without the red coloration but babies may show some red when they are young. Imported Blue Velvets on the other hand come from the black line.

 

Many blue diamond shrimp may be blue shrimp that may or may not have carbon rili coloration, but they are not blue carbon rilis. Blue carbon rilis are a lighter blue in coloration.

Blue Dreams are usually without black coloration.

I'm not entirely sure how imported Blue Velvets fit in here... unless they are actually Blue Dreams by another name.

 

It gets really confusing, especially when you come across shrimp labeled as "Dream Blue Velvet" or "Blue Dream Diamond". Like, which is it?

 

And there are these charts here.... but I don't know how accurate they are. Further DNA analyse may be required to determine if all shrimp currently labeled as Neocaridina davidi are actually one species or if they might be separate species 

 

 

In short, there is no world-wide grading for all the different colors. The only thing everyone can agree on is the grading system for low grade cherries to high grade cherries - aka Painted Fire Reds... and what a bloody mary is, a chocolate, a carbon/black rose, a rili (pattern type) and..... that's about it. There are at least 3 different names for different yellows, at least two different types of oranges (and I hate the name given to one orange type!), at least two types of greens (I'll never be able to think of green jades without also thinking about one with ellobiopsidae/green fungus but seller swearing USA bred shrimp not from imported stock and it's berried.... oh, and seller is a fish vet? supposedly certified, but seems self proclaimed... -shrugs-), who knows how many varieties of blues... and some people will sell low grade blue of one variety as a different variety of shrimp... as an example, if Blue Dreams are bred from Blue Diamonds, and someone has a colony of Blue Diamonds, they might sell the culls as Blue Dreams even though they aren't *really* Blue Dreams.

 

You can look up a chart (not sure where it may be here) for grading cherry shrimp, which should be able to give you an idea of how to grade other colors.

 

 

 

Back to subject of bloody mary... the best ones I've seen are actually from another member of this forum.

 

 

Compared to bloody mary from another member.... they are still nice looking shrimp (again, pictures do not do them justice!) but you can tell that they aren't quite as good by at least comparing the legs.

      Yah idk if it would do heaps of added extra for a tank ... I would add more air via a pump before I spent $15 on the device

      Don't know about effectiveness on breeding, but additional oxygen in the water can't go wrong. It's probably better for overcrowded tanks.

      Any Update on the effectiveness of this on shrimp and breeding?

      Id put in maybe a liter or 2 of water (1cm of water in the tank) and put in a couple handfuls of substrate at the base just to help, the other substrate to them cover it which will have the main contact with your water allowing for the buffering effects (and the colour difference if there is one wont be noticed).

      I currently have a small pipe heater in the current tank that i can use for the new one, that technically makes my new project cheaper because i now don't need 2. can i get dimensions of this thank fully assembled including the top cover just so i can determine if i need to adapt my shelving. i don't mind poking out a corner of the tank from the shelf so i can do water changes and i can lift the tank onto another surface for heavy maintenance if necessary. Im really just interested if there is space for feeding without moving the tank.
