  1. Switching over to regular shrimp salts might be a good idea. It would at least remove one variable. And SS is cheap.
  2. I know what you mean about specialty stuff being $$$. That's one of the reasons I like Salty Shrimp. It's cheap LOL! I've had bloody marys since 2013 or so. Every few years I have to restart the colony because the color drifts. Sometime around 2016 I restarted them because I felt I was culling too many light ones. I restarted it again a few months ago because I felt they were getting too dark. So, it happens. I think it happens with all shrimp. Even if we're diligent with culling, things can start to change after so many generations in so many years. 😊
  3. It could be genetic drift... Bloody Marys came from chocolates. Looks like some of them may be heading back that way possibly. Some of the ladies do turn dark as they get old. Seems to only happen with the females. I don't think I've ever seen it happen with a male. I think it has something to do with pregnancy and hormones. That at least seems to be the norm for me anyway. So yes, some older ladies can turn dark, and opaque. They kind of start to look more like large painted fire reds. But that older female in the first picture (on the right) looks kind of brownish. And there are some in the pictures that are way too young for that to be happening yet... So I think it's just genetic drift back to chocolate. I'd cull the darker ones, and only keep your best colors. Then let the best colors breed back out. They look pretty healthy though. And I wouldn't bother reducing the mineral content. They really should have a GH of at least 5 for good molting. I keep mine at 7. I honestly don't know how marine salts would effect them... If culling doesn't solve it, you could try switching to minerals made for fresh water. Salty Shrimp makes a GH/KH+ version and it's pretty cheap. It's a dry powder and a jar lasts forever!
  4. You might be okay with that. But I'd wait until the tank was matured before adding them to make sure that it was well cycled and all the ammonia/nitrate was gone first. And I wouldn't add any more. Keep the population low. Let the tank establish for 2-3 months and then test it to make sure everything is cycled. That will give time for some biofilm to form for them to eat as well. A Walstad bowl is on my bucket list. They're beautiful!
  5. I don't have any experience using marine salts with freshwater shrimp, for my caridinias I usually use Salty Shrimp GH+. But I don't have to use it with Neos as my well water is fine for them. It sounds like the study was doing that as the shrimp had parasites and they thought the salts would help... How large is the tank? Is it a larger tank? Or a smaller one?
  6. They probably would. Google "shrimp interbreeding chart". That will bring up some nice charts and tell you which kinds will interbreed and which won't. Then you can google the possible results from what ever cross you're thinking of. Crossing different colored Neos will often result in degraded colors so I wouldn't do it. Crosses of Caridinias and others can be fun, but I wouldn't do it in a large display tank. Culling out to get what you wan't will be difficult especially if it's heavily planted. Cross breeding is better done in a smaller tank that's easier to work with. But that's just how I go about it. Others have mixed them up and had a lot of fun! 😊
  7. Yeah, serratirostris makes sense! Ninja shrimp. They do like to change colors, it's what they're known for. The upper pics look like they're orange (at least on my monitor). The last picture looks blue. What cool shrimp! 😊
  8. What's the temperature of the tank? Shrimp do have an ability to change color somewhat... Is the temp. to high? Could it be stressed? What kind are the other shrimp in the tank?
  9. Totally jealous LOL! I'm getting ready to re-do the 40B in my dinning room. Definitely putting in more buce! That blue ghost adds a nice color contrast...
  10. Nice catch Shrimp Life! The fish would probably appreciate it a little warmer, but 23 ought to be fine for everybody.
  11. I don't think an air conditioner would do it as they pull air from inside a room, cool it and push the same air back into the same room. They don't take air from the outdoors. So there would be no net change. It would need to be something like an exhaust fan, but in reverse so it took air from outdoors and pumped it in. Well, now you've got the Science Nerd in me going LOL! I've always wanted to try the light experiment, just never got the time... It would take probably 2 months at least. If you try it, try running the lights for only say, 5 hours for a month. Then increase it to maybe 10 or 12 hours. That kind of thing will trigger plants to bloom or fruit. And if there's a window in the room, pull the shade and close the curtains to make it as dark as possible when the lights are out. If there's too much light leaking in, it might be enough to trigger a normal day cycle for them, as opposed to the artificial one you're trying to create. And it doesn't take much. Plants at least are very sensitive to that. The only other thing I could think of that might cause it would be temperature. I don't use heaters in any of my caridinia tanks, so they're always at room temperature. I live in Maine (USA) so room temperature can be around 67 in the winter, whereas in the summer it climbs to the upper 70s as I don't use air conditioning in the room that I keep the tanks. Maybe they sense the gradual temperature change? Do you use heaters in your tanks?
  12. Yes, but did you ever try varying the light cycle? Or is it kept constant all the time? It's the shortening of day-length that causes leaves to turn red in the autumn and many plants (like apples) to form fruit. But that's for plants. It was just a thought... The barometric pressure data looks like an interesting possibility. But how could you prove it? You'd need a room in your house that you could manipulate the pressure... I worked in a positive pressure clean room for many years when I worked in a lab. The room was sealed and air tight. Then fans blew extra air into the room to increase the pressure inside, so there was always a whoosh of air rushing out of the room when you opened the door. The idea is that dust, bacteria etc. is less likely to enter the room if air rushes out rather than is pulled into the room. Then you'd have to have something to control the pressure at a set point... It'd be a tough one to prove. And probably impractical to use it to induce breeding for most people. But it's a great hypothesis! 😊
  13. I love small fish!! I have 5 tanks of small schoolers! I'd go with the filter foam. Covering filter intakes with shrimp is an evil necessity. It will reduce the filter's ability to clear the water as the larger particles won't get through so they can't be removed by the filter. But if you don't have one, you'll loose the babies... Small peaceful fish will still eat the babies if they can catch one. Even something as small as a rice fish or a chili raspbora. The babies are that small. The only fish that won't eat them are otos. That being said, I keep neos in all of my fish tanks. Once they get breeding, the fish will get some, but some always manage to escape and keep the population going. And adding neos to a community tank is a great way to add interest with a very low impact to the bioload. I don't tend to keep caridinas in with fish, unless I have an overabundance of them. Caridinias don't breed as prolifically as Neocaridinias. That's why they're pricier than Neos. Since you don't get so many babies from them, every one is precious. Most folks don't mix caridinias with fish. And most folks who keep caridinias use sponge filters in the tank as they won't suck up any babies. I do have some PRLs in a tank with small schoolers, but I only did that because I had another shrimp only tank with too many in it. So I put some PRL culls in with the fish... It looks really nice and if the population died off tomorrow, well I always have more culls LOL. I certainly wouldn't have done it with my best shrimp. So I'd just go with the filter sponge. Lots of folks use filter sponge for this purpose. Coarse filter foam works best as it impedes the water flow the least but will still prevent most babies from getting sucked up into the filter. It may shorten the life of the filter, but not too badly. I usually get 3-4 years of life out of a marineland canister filter with foam on the intake before the motor finally goes. And I've done it with HOBs as well. Maybe I'd get an extra year of life out of one if I didn't use it, but then I wouldn't be able to keep the creatures I want. So don't worry, it won't blow the motor overnight unless it was already getting ready to die. What's that in the bottom of the breeder box? It looks like coarse foam.... If the foam that you have is too fine, just rinse an old pair of panty hose really really well. Let it soak for a few minutes in water in between rinses to make sure all the soap is out. A final swish in some water with dechlorinator would be good. I've used panty hose in an emergency when I was low on filter sponge. Tights tend to be heavier material than panty hose, so they might impede the flow more. If you still feel uncomfortable with that, I suppose you could just leave them in the floating breeding box. You might loose the least amount of babies that way anyway. Just make sure the water gets changed and there's some kind of aeration or water movement. But once you have a few berried ladies in your community tank, you'll probably be okay if it's heavily planted. Yeah, the fish will get some. But they probably won't get them all. 😊
  14. Cardinals are on my bucket list!!! They're gorgeous!!! 😃
