I'm going to give credit, where credit is due and leave this open for discussion. This comes from one of my mentors and colleagues Ciaran. It's not set in stone and I'm sure some people will argue, but this was his guide he wrote.

Grades

A Splotches of colour (3 red bars typically with a small amount of red on the tail. White is generally inconsistent and can look slightly patchy.)

S+ Three EVEN FULL Red and White bars

SS 75% white with 3 red spots decreasing in size from head to tail

SSS 85to 90% white with 1 or 2 spots decreasing in size from head to tail

Where it says red, change it for black to grade CBS.

I will stand by another post of mine. This is only acceptable for RED or BLACK striped individuals. Shrimp with brown or maroon stripes should be classified as culls as they adhere to neither colour form.

If we can agree on this, we can move onto finding photographic examples of each

There's several well regarded reference on the net with regards to the grades, in terms of the pattern..etc. so rather then re-invent the wheel, I would suggest we just use it. Just my opinion though...

I think the main issue in Aust. is the quality, i.e. richness of colour, depth/thickness of colour etc.... If a shrimp was presented FS, similar to the attached pic, with a hino pattern (SS grade), but has very poor red/white colouration, how would we grade this here in Aust. I would Personally consider it as a cull, and instead of the $25-$50 for a typical SS GRADE, sell it for $10 or give it away.... No I won't use my shrimps as fish food...LOL.

Another example (pic below)...Is this regarded as a A or S (tiger tooth) Grade ? And is the red/white rich enough or the depth/thickness strong enough to warrant it a A or S ? Well regarded / international breeders would perhaps say no ? (Imke, Alvin or Dean ?), but here is Aust, we would perhaps generally say she's A/S primarily due to the pattern, and enough colouration on her ?

I think this is the decision we need to make....drop her down one grade because her coloration isn't perfect ? i.e. B Grade ? Or consider her as a cull ? i.e. $3-$5 or giveaway ?

S Grade - White with 3-4 bands of red/black. Solid Colouration.

S+ Grade - Same as S Grade but with a tiger tooth pattern on the centre band.

SS Grade - Mostly white with 1-2 bands and 1-2 dashes of red/black. Solid colouration.

SSS Grade - Mostly white with one central red/black dash and 0-2 smaller ones. Very Solid Colouration.

no entry is referring to the middle red pattern. the red circle with the white line through the middle as I looks like the road sign.

I actually disagree and would regard it as an s plus due to the slight red line/marking directly underneath the no entry pattern. Look properly

      Shrimp molting before eggs are hatched

      By sdlTBfanUK · Posted

      I would hazard a guess that perhaps those eggs were unfertilized and thereby unviable? Did the eggs change colour, usually yellow to grey as the yolks used up, or any eyes in the eggs. Is your water ok, using RO remineralised and the parameters in range, as I have heard others say that if the water isn't good it can 'force' a molt? How is it going overall, do you have a good size colony in the tank, you may have reached 'maximum occupancy' as a tank can only support so many occupants.

      Shrimp molting before eggs are hatched

      By beanbag · Posted

      Hello folks,  The current problem I am having is that my Taiwan bee shrimp are molting before all their eggs have hatched.  Often the shrimp keep the eggs for 40+ days.  During that time, they lose about half or so, either due to dropping or duds or whatever.  Shortly before molting they look to have about a dozen left, and then they molt with about half a dozen eggs still on the shell.  Then the other shirmp will come and eat the shell.  These last few times, I have been getting around 0-3 surviving babies per batch.  I figure I can make the eggs hatch faster by raising the water temperature more (currently around 68F, which is already a few degrees higher than I used to keep it) or make the shrimp grow slower by feeding them less (protein).  Currently I feed Shrimp King complete every other day, and also a small dab of Shrimp Fit alternating days.  Maybe I can start alternating with more vegetable food like mulberry?  or just decrease the amount of food?

      Shrimp and meds containing gentian violet

      By ngoomie · Posted

      Yeah, cancer risk was a thing I'd seen mentioned a lot when looking into gentian violet briefly. I kinda just figured it might only be as bad as the cancer risk of malachite green as well, but maybe I should look into it more. I've been doing a pretty good job of not getting it on my skin and also avoiding dunking my unprotected hands into the tank water while treating my fish at least, though. Maybe I'll just not use it once I'm done this course of medication anyways, because I know a store I can sometimes get to that's pretty distant carries both malachite green and methylene blue, and in pretty large quantities.

      Shrimp and meds containing gentian violet

      By jayc · Posted

      Can't help you with Gentian Violet, sorry. It is banned in Australia violet for potential toxicity, and even possible cancer risks. I thought it was banned in Canada as well. At least, you now know why there isn't much info on gentian violet medication and it's use. But keep an eye on the snails after a week. If it affects the snails, it might not kill them immediately. So keep checking for up to a week. Much safer options out there. No point risking your own life over unsafe products.

      Shrimp and meds containing gentian violet

      By ngoomie · Posted

      Hello! I have a tank that currently does not contain shrimp, but does contain neon tetras which I am currently treating for Ich, as well as some bladder snails. Shrimp will be a later addition, likely cherry shrimp but I'm still doing research just to be sure. Initially I'd intended to buy some sort of Ich-fighting product that contains malachite green after doing a decent bit of research on it, most of which indicated that it should be shrimp-safe so I'd be good if I ever needed to use it again once shrimp were actually introduced (though I should note I'm aware shrimp can't get Ich, I'm more wondering in case the tetras could get Ich again, or something else that responds to similar medication). I ended up not being able to find any MG-containing products without either having to travel quite far or wait multiple days for delivery (which I was worried could lead the Ich to be fatal), and ended up picking up 'Top Fin Ick Remedy', a product that contains gentian violet which is a triarylmethane dye like malachite green. The bottle has two slightly differently worded warnings about its use with invertebrates ("not recommended for" and "not safe for" respectively), but when I'd been researching malachite green, I'd also heard of products that contain MG but not any other ingredients that would be harmful to inverts still being branded with warnings that they could be harmful, just as a "just-in-case" since the manufacturer didn't test it on any inverts, and I'm wondering if maybe it could be a similar situation here. I'm having a very very hard time finding information about gentian violet's use in fishkeeping at all though, it seems currently extremely uncommon. What I will say though is that I'm on day 2 of treating my tetras with it, and the bladder snails seem just fine -- in fact today I noticed what looked to be a bladder snail that appeared to be newly hatched (because of its size) that I hadn't seen before that was zipping around the tank without issue. But obviously, shrimp are not snails, and bladder snails are also notoriously hardy little guys, so what I'm seeing right now could easily be totally inapplicable to cherry shrimp. It might even be inapplicable to other species of snails, for all I know. Has anyone else here ever used anything that contains gentian violet in a tank that actually does contain shrimp? Were they okay, or should I make sure to not use it once shrimp are added?
