Why are my Shrimp going crazy?

Recommended Posts

perplex

So here is a video of what is happening

 

i was watching them for about 20 mins and they kept going, id say over 30 mins as i didnt see the start of it, could be alot longer. Edit - 2 hours later some still going nuts lol.

they are just swimming around going nuts, is this there mating dance or something?

anyway after 20 mins i saw them starting to attack one, my guess is that it was a female, i saw her molt while 3 shrimp were attacking her, after that they kept picking on her abit, she looked exhausted... she kept swimming to the top of the tank and then falling back down, upside down, she did this couple of times and shrimp attacked her alittle so i though, id make them stop, so i gave them food, this seemed to help, i also decided to catch her and put her in a net at the top of the tank with a rock, so she cant get picked on, ill see if she has removed by tomorrow, im giver her a 50/50 chance of being alive.

 

now one more thing, i can force them to do this dance, i found out when i decide to clean my filter, just having the water stop moving they start going crazy as well, here is a video of that, it is 30 mins long but just skip along and you will see

but as soon as the pump goes on they kinda stop and go back to normal, so i guess its about different from the first one, since thats been going for 2 hours now...

at the 15 min mark they start going crazy :P

Most people will say it's because a female has moulted but it looks like all your shrimp are doing it. First I suggest you do a water test for ph, ammonia and nitrates as a minimum in case there has been a spike of some sort. Have you done anything different, sprayed the house , flea bombs, paint etc? Have you done anything to the tank, water change , added something, fed veggies that may be contaminated, used something on your hands like oil or soap or aftershave. Recently someone had sprayed their house with pesticide and had a very similar reaction so think what has happened in the last few hours

Sorry to go off topic from the original post but Ineke did the person who sprayed the pestide have the inside or outside done?

He was spraying outside but didn't cover his tank , the fumes must have entered the house - he may have brought it in on his clothes. He lost the lot unfortunately

I recently wrote up how to make your tank safe when spraying.

what do you put with the water when you do water changes? any black water products?

my shrimp dance when i add IAL tea ( black water) to the tanks

You need to add Blackwater products slowly or well mixed with the new water as it lowers the ph which may affect the shrimp until it's mixed with the tank water thoroughly.

Very interesting @perplex

I've only seen similar during mating. Well I think it was mating.

I have also seen my CRS go nuts and attack a female shrimp. I was too late to save it unfortunately. Did not have time to grab a camera either.

I'm equally in the dark about what happened. Never saw it happen again.

well i have 2 videos, the one that lasted 1 min they are more active, where the one where i change my filter they are more chill, both are weird, and more weird i can make it happen

 

Update - the shrimp seem to be back to normal today, the female i put in a net decided she would climb out of the net...so i got no idea if she is alive...

this is how the net was, but there was glass ontop of it. the sides of the net was out of the water as you can see, i did have something for the shrimp to hide in, but took that out, so i have no idea how she got out, there are no holes in the net and there was hardly any room at the top of the net and between the glass, but she still magically got out...

 

so i guess shrimp can move out of water kinda

Yes it's mating for sure. look at the first video from 0:30 typical a male who is in pursuit of a female (of what he thinks is a female).

Oh and the second video is different. This is a something that happens here too. The sudden stop of current gives them something to start moving around. Not sure why, a sudden drop of O2 is not possible I think. Must be something else, the sudden change of their environment, start looking for a safe spot? Like in the wild, when the current of a small stream stops, something must be going on and the will search for deeper water?

      Hey guys, I thought I’d just make a single topic for my community tank, so I stop running around in other chats asking the same questions 😁. I’m going thru a big change in the tank at the moment, so will likely update in the morning with photos once the cloudiness is gone. Be prepared for a possibly very long message about a 10 hour process 😂.
      Cheerio!

      Hey guys, just found an add for this website showcasing a cool-lookin native algae eating shrimp.
      https://algaeeatingshrimp.com.au/products/australian-algae-eating-shrimp
      Anyone heard of these before or own any? My interest was peaked by the claim that they eat hair-type algae, as I have some on my crypts and lace fern that I cannot remove. And for a price of $4 ea, and super easy parameters, they sound pretty doable! 
      Tell me more oh great SKFians! 😁
      (or feel free to point me towards an already existing page)
      post-note: have you/do you keep these grubs? Seems like your sort of thing.

      Hey guys, I’m going away for a few weeks and having a neighbour take care of my tank, as they are already gonna be caring for my cat during that period. I’ll be away for 2 and a half weeks, so not a huge amount of time, but the neighbour doesn’t have any experience with fish or shrimp tank maintenance.
      The tank will be fine without a water change during that time as long as I do one before I leave, I know that, but my 2 main problems are feeding and stopping my intake sponge from clogging up.
      For feeding I was considering getting a couple of pill boxes, like the ones that have seperate compartments for each day of the week, so I can set a certain amount for each day, and which foods.
      But for the intake sponge, I’m pretty stumped. My current intake is a sponge filter connected to the intake pipe, but it’s been clogging up once or twice a week due to how fine it is (and how messy my fish are). When it’s clogged, it puts strain on the canister filter’s motor, and that’s not good. I don’t trust her with cleaning it safely, plus I’m only paying her for 5 mins in the morning, and 5 at night. I’ve considered a mesh intake, but it looks like it could hurt a fish if it went past it quickly... plus I can’t check the size of the inside where the pipe could go as the only one I’ve found would have to be posted.
      Are there easy alternatives that I wouldn’t have to mod, or do intake sponges come in courser versions? (I haven’t checked).
       
      Any input would be appreciated!

      Hey guys, I’m really wanting to get freshwater crabs, and the only ones I’ve found are A. Lacustris and A. Laevis. I can only put them in a 110 L community tank for now, but may have another option in the future. The tank is stocked with a large school of ember tetras, some rocket killies, some endlers, some tangerine tiger shrimp, and a pair of apistogrammas. Rare aqua advised that A. Lacustris would likely be eaten by the apistos, so the obvious choice would be A. Laevis, because they’re larger... right? But I’m worried that they might predate upon my shrimp, so wanted to hear some advice and opinions from more people with experience keeping these crabs.
      Cheers!

      At the time, those babies grown and had babies, those babies also had their babies, during that time, I did not add bacter AE, I never knew what it was, and I was only a beginner, @sdlTBfanUKhelped alot along with @jayc oh, had average 20 babies for each mother shrimp.
    • sdlTBfanUK
      I agree that there probably likely to have more survive with food but if you have 10 already (and there are probably many hiding) that is a good start and it is probably better to get half a dozen each batch (month) than over-run too quickly! You should be fine not using baby food at the moment with the number of babies you have! I had extraordinary survival rates in the original 15L tank which I assume is because they all got some food being such a small tank. Within months of the 8 shrimps breeding I got about 150 babies - it was panic time to get a bigger tank set up! Simon

      I am more of a give a plant a go and it either lives or not, though I don't think anything has died off thus far! I don't know what plants are available to you but they are a personal choice for you to make so just see what there is? I wouldn't use CO2 but if you do decide to use the Flourish excel I would do it slowly starting with half dose etc! I have had algae before with new tanks but it has just cleared up with time on it's own, I guess when the whole system has sorted/balanced itself out! Simon

      Maybe around 10 or so I know that many people claim to have increased baby survival rate by dosing various baby foods or Bacter AE.  What has your survival rate been?
    • Crabby
      No plants ‘require’ CO2 so to speak, but it helps boost growth. Flourish excel is basically bottled CO2, so you could do that. Most red plants will just grow a bit greener without CO2. I have some variety of Ludwigia repens, and it stays pretty red, as the leaves reach higher toward the light. But the best thing to do is just try something. Test it out, see what works and what doesn’t, because nobody‘s tanks are the same.
