    Breeding and culling process

    Going back to culling , i would like to point out that removing too large a proportion of the colony you wish to improve , gets your there faster , but you reach a point of no further progress for lack of genetic variability. I tend to cull the worst 20% of my colony once a month and observe a slow steady improvement. Hopefully my colony will continue to improve Long into the future. I have learnt about population genetics when i was interested in breeding fancy fowl, and kept up to date now that i am interested in shrimps and horses. The laws are the same.the greater the breeding population and the lower the percentage that is removed from reproducción, the healtier and more prolific will remain and the further the progress in recombining desirable caracters. A severe rate of culling makes your population very homogenous early on and improvement stops

    Shrimp ID???

    I'm still new to the hobby but they kinda look like other post (could be wrong, but he called them glass shrimp) https://r.tapatalk.com/shareLink?url=https://skfaquatics.com/forum/topic/11301-what-kind-of-shrimp-are-these/&share_tid=11301&share_fid=50791&share_type=t For the last pic it looks like a pinocchio shrimp (Caridina gracilirostris). Maybe someone will correct me. Sorry couldn't help anymore. Sent from my 2PZC5 using Tapatalk

    Dealing with warm water

    Newer A/C units now have auto on/off features. Maybe it's time for an upgrade @Zoidburg 😁 The things we do for our shrimp!

    No3 rising very quickly

    I really enjoy cycling a tank from zero. Find fascínating the invisible process seemingly Out of the blue , where ammonia rises, leaching from the substrate ( always use Ada amazonia or help shrimp substratos) then ammonia turns into nitrite and those two dissapear and you are left with nitrate, al i had to do was wait, i also use seachem matrix or pondguru,s ultimate and that ends Taking Care of nitrate too.

    Good or Bad Idea?

    I think it might help to understand what water parameters you already have and what substrate. As far as the bird mineral blocks go? They should, in theory, be okay, however I'd be concerned about the metal that's in many of them. The metal that's meant to be tied to the bird cages. Wouldn't personally use it, because if extra calcium was required, I'd just add it from a remineralizer or get some form of calcium in another form to add to the tank.

    My tanks

    update Taiwan and pinto tank go very well, i have 80+ babies... But they are grow very slow. Crs are over polulation on two 100lt tanks Cbs are 200+ from 4 shrimps that i start. f1 tibee x pinto , tibee x crs, tibee x cbs There is bad thing i have 20 tanks , and i dont have a space for shrimps.

    Shrimp Diseases and Diagnosis

    They don’t appear to be lethargic, and are still grazing. The symptoms are the discolouration and two deaths. Shrimps have been in this tank for 25 days.

    Nematodes?

    Phew! Funny how the conversation started off as something completely different, id'ing worms, to something that lead to identifying a possible issue with the health of the tank. Go Team!

    Trouble with grading shrimp morphs

    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.

    OMG what is this creature!

    Just for some closer in case anyone reads this and has the same issue. As per the other post that you linked, seems like you have detritus worms. Not harmful. You don't need to do anything at this stage.

    What shrimp is?

    Ignore the colour, as Masapi can come in many different colour morphs. But always, the rostrum is very long. And stripe in the middle of the head as Zoidburg mentioned. Try to catch the shrimp and place into a breeder box for photos. Get a close up side shot of it's head.
  18. Ok nicpapa I'll take it down a bit more if that's the case, today I've seen two crystal berried so it's definitely working

    Once a male red cherry, now a blue cherry?

    Ruling out lighting, as ive been observing for a few days at different times of the day when light was on I feed my shrimps a mix of spirulina wafers, spinach, Hikari shrimp cuisine so I don’t think it’s diet as all shrimps display an even deeper red especially when spirulina is fed to them Possibly genetics as far as I can see, it has a undergone of blue sort of like a blue body red rilli This little guy’s been like this colour for a week now, where as the others have attained their colours again. Could be stress? Pics for reference next to a shrimp into the box from the tank Sent from my iPhone using Tapatalk

    Advantage of RO or rain water?

    i use salty shrimp gh + to remineralize my 2 tds ro water and achieve gh 4 at a tds of 60-70 and that is what i use for water chánges. Tds in the tank stays arround 90 to 100. .for Taiwan bees. Good breeding and baby survival

    Madagascar Lace Plant

    Going to show my age a little now, but years ago I remember seeing Madagascar Lace Plant for sale in a Fish Shop in Mackay, and as a young teen although I fell in love with the plant I never had the slightest hope of ever buying one because even back then I think they where selling for something like $50+ and this was when I only had a $5 a week pocket money income from my parents. Then for years I never saw these amazing plants again, and thought they must have died out in Australia (or been so rare I would never see another one expect in pictures), so imagine my surprise when checking on Facebook I found a person selling my dream plant, and I was actually more or less in a position to afford it!!!! Of course it was a no brainer and I contacted them immediately to secure a plant. Its still only young but I have big hopes for it. The bonus for me was the seller said they where growing the MLP low tech so no ferts or co2 injections. I read up some advise and found that when the plant goes dormant (most likely in summer) its best to leave it in the tank with warm water (bonus for me in central QLD since the struggle has always been trying to keep tanks cool), and that it does best with other rooted plants like swords near it. Perhaps a symbiotic relationship occurs much like certain fungi with Grass trees. Also some shade is advised I guess for the young plant/ leaves since a mature plant will easily have leaves reaching the surface of the tank. Has anyone else grown this plant and what has their experiences been? Any other tips? The cherry shrimp have already given a good going over and it looks like the snails have no interest in it, the main trick is going to be keeping the corys from up rooting it. It is planted in a sand substrate with some rounded river gravel, at the far end of the tank away from the HOB filter that hangs on the side of the 4ft tank rather than the on the back of the tank. The light is a LED I think tropical grow light that doesn't go the full length of the tank although the MLP is planted down the best lit end of the tank with a sword in front of it, a curly leafed type of val near it and various Anubius and narrow leafed java fern attached to wood also near by. Also a very tall anubius to the front of it that does give it some semi shade.

    Is this the start of green or gold?

    Food wise my shrimp pretty much get as a staple tropical fish flakes daily, its only really on the weekend or may a couple of times during the week (if I think of doing it) that they might get some catfish wafers, algae wafers, crayfish pellets, Wardley Shrimp Pellets (made out of shrimp for catfish and loaches not necessarily made for shrimp) or the odd shrimp ring food. So its a fairly varied diet with the odd mulberry leaf or IAL also given to them. Depending on the tank and other inhabitants my other shrimp also get access to micro pellets and first fry powder. The last is mainly for the benefit of the riffle shrimp.
  26. Has any progress been made in figuring out how to keep riffle larvae alive? From what I've read here and elsewhere, it's not entirely clear whether it's an issue of chemistry/hardness or food. This is a basic but important question, and I think it's easily answered by running a few experiments using water drawn from a creek where they naturally occur. Is there anyone here that can help?
