  1. I've seen this in my low-grade bloody maries as well. It happened when I moved them from their preferred parameters into more of caridina parameters. Over time they eventually turned brown/black (and a lot of them died off). Not having put in the effort to isolate and reproduce this, it just seems like a stress response. It sounds like you have a good understanding of water parameters so I'm not sure what is triggering the response, wish I could be more helpful there. I would suggest swapping reef salts for Salty Shrimp GH/KH+ for lack of anything better. I'm skeptical of drift since the time period is too short, that wouldn't just pop up on a couple months.

    Those look nice! My timing isn't great as I'm about to go off the grid for a week. I'm going to get my tank fully stabilized so I'm not in a huge rush. I was thinking of getting ~10 so I maybe by then you'll have more stripeys available That said, if you're trying to move them (say to prevent breeding with the royals), give Vorteil a shout. Thanks!
  3. Caridina serratirostris? A lot of them have more stripey patterns but a couple pictures online look like what you have. Known to change colors too. How big are they?

    You've saturated the market! Very cool, thanks for getting back to me! How much are you pricing the stripey ones? Are they more like OEBT culls (blondes, light/no blue) or just non-royal OEBTs?

    WTB OEBT

    Hi all, I'm looking for some OEBT (preference for non-royal, I'm a sucker for the stripes). I haven't seen them around in a while, looks like they aren't as fashionable anymore. wyzazz has kindly put me on his list, are there other fellow shrimpers who still keep them? I know Blue Crown carries some nice ones, curious to see if I can source from hobbyists, though. Thanks!
  6. Since no one on the forum has bitten yet... Have you checked our Ark's stock on Aquabid? While not on this forum, he's been in the shrimp game for many years and his cardinal shrimp will likely sell for a lot less than a more commercial seller's. Good luck! Heard they require some very finicky parameters.
  7. So much buce! Please post a follow-up picture in a couple months, this will look great grown out. What is the darker looking buce in the middle and the substrate? I also just did a bucescape myself but the greens don't pop as much so it looks kind of drab. Jealous!
  8. Tiger shrimp and CRS/CBS are not the same and are generally kept in different parameters. Tigers would most likely be in neo parameters depending on where you get them, while CRS/CBS would be caridina parameters. Take a look at this:https://www.discobee.com/blogs/news/17030569-dwarf-shrimp-water-parameters I also recommend you do some reading on water parameters and buffering since it sounds like that's new to you and you want to have a handle on that before buying any livestock. Specifically, look into gH, kH, and pH. I don't have any links handy but it's covered plenty of places (including on this forum) with a bit of googling. To answer your direct question: - for neo parameters https://flipaquatics.com/products/shrimp-mineral-gh-kh?variant=43063556100 - for caridina parameters https://flipaquatics.com/products/bee-shrimp-mineral-gh?variant=43063611268 You actually do want to mess with water chemistry, like by adding specific minerals to promote shell growth or to keep the water in specific pH ranges, for example.
  9. Nothing of note, I've been snapping some pictures here and there but the (few) shrimplets that survived to this point look very much like their tangtai parents so they're not particularly interesting. The really cool looking ones seem to have died off. Not sure why, my water seems like it's within range. I wonder if the ones that look more tibee-like also inherited the blue-bolt sensitivity/hatred of my tank, while the TT-phenotyped shrimplets got more of the TT hardiness, explaining why those are the ones to survive. Either way, the parents are still breeding so I'm keeping my eye out for cool-looking babies. It's slow-going with the survival rate being so low in my tank
  10. Got it. What confused me (and still does) is why you assume that all of the 20% of heat waste generated by the LEDs get transferred to the water. As you say, it's an engineering problem and I won't pretend to be able to solve it, but I would imagine that the amount of heat transferred from the LEDs to a water column 4-12" below (depending on the setup) through convection is relatively low, not 100% of the heat generated on the light fixture (air is a bad conductor, there's a lot of air in the room, and hot air tends to rise anyway so the convective transfer seems limited). Not saying it's negligible, just that it would be a fraction of the 20% you use in the calculated rate of temp increase. Radiation, on the other hand, seems like it could account for a lot. Soils absorb roughly 80% of the light that hits them, so if you had an amazonia bottomed tank with no plants, you'd be looking at a decent amount of heat generated by the LEDs. (37.533(0.8*0.8))/(0.999*62.31*2.94)= 0.13 F/hr dT = 1.05 F in 8 hours. ...so not as much as the pump, but still something! One easy way to get around it is to lower the light output (dimmer), which would also decrease the waste heat/convective transfer or go with a higher albedo bottom in the tank. Fun stuff!
  11. I’m confused by your LED heat waste calculation. I’m probably misunderstanding but are you assuming that 20% of the LEDs power draw is converted to heat in the water? Why?
  12. Yup, that’s scutariella. They grab onto what they can, sometimes head, sometimes rostrum. Google images has examples of both. Luckily it’s an easy fix!
  13. Are you monitoring nitrates while doing this? It could be that the purigen is stripping the water of nitrates (which plants need to grow) and other nutrients. If you had other junk in the water as well (or nitrates >20-30ppm), that might have explained the baby shrimp deaths. Fertilizing with Purigen in the tank seems... wasteful? I'm guessing you'll burn through both Purigen and fertilizers. That said, maybe your nitrates were low the whole time and it was something else in the water that was killing off the shrimplets. Either the source is still there (different problem you have to solve), or the Purigen took it out (problem taken care of).
