Possible tank invader?

Recommended Posts

FrumpyJack

I have only been keeping Neocaridinas for about two months now, I have 10 blue dream neos in one tank, and 12 orange neos in a separate tank. The tank with the 10 blue dream neos has been slightly problematic though because it's a smaller tank and waste builds up a little faster.

That being said, can anybody ID this swimmer in my shrimp tank? There is only 1 that I can see, it appears to have an exoskeleton almost like a shrimp, and it swims at the surface of the water by whipping its tail. I don't think it's a baby shrimp fry because I'm just now seeing my first female berried up and there haven't been any births before, but I suppose it is possible a fry snuck in with my order. Any help would be appreciated 😁

The quality isn't very clear but to me it does look like a shrimp. Mine sometimes swim like that at the surface when being fed.

Fingers crossed you have your first baby shrimp.

Yeah, it's hard to get a clear picture through the curve of the glass and looking up at the light. Sorry about that. 

I do have a nice biofilm of bacteria on the surface of the water in that region of the tank where the water is still and the specimen in question seems most interested in feeding on the biofilm

Catch it, then take a close up, macro shot that is in focus.

No one is going to be able to help you identify that.

Oh, you can read through this post to see if you can id it https://skfaquatics.com/forum/topic/1384-aquariumtank-creatures-101/

I tried my best with my phone camera. I don't think it's a baby shrimp IMG_20181028_111123.thumb.jpg.9b59b70e3c69f36905d5765e1d5a56f1.jpg

Thats freaky and doesn't look like a shrimp that I know of. If you haven't already fished it out then that would probably be a good idea ASAP (it may have eggs or something) and if you want to keep it until you identify it just put it in an old jar. I would flush it though, it doesn't look like something I would want in any tank!

Hope you get to the bottom of it?

Don't know what that is either.

But it looks small, if that i a glass cup/jar you have it in.

 

Is you tank an open top tank?

It is tiny. It's only about 1 mm or 1/16 inch in length. I pulled it out of the tank and into a smaller cup to take the pictures and it died in the process. Upon further inspection of my tank though, there appear to be a few more in there. 

They seem to only stay up at the surface of the water where they appear to be feeding on biofilm and algae. I'm wondering if it's a relative of detritus worms. 

Other than the shrimps, I only have one Siamese flying fox fish in the tank and one mystery snail and they appear to be quite healthy and active with no symptoms of parasites

It's an insect's larvae of some kind. 

I'm surprised the fish isn't eating them all.

Try to get rid of them manually by catching them if you can.

I'd guess a mosquito

      I'm starting a brand new #neomix tank.  I won't be adding or taking out any shrimp, just documenting developments along the way.  I'm interested to see if any new variants develop, and what the tendency towards brown is.  I'll be sharing updates on my channel if you are interested in following along.   Enjoy!  #shrimptv

      Green shrimp  I looked at one of my green Neocaridina under the microscope, and I'm trying to determine if all green shrimp are like this... or just mine.  Any insight from other green or jade shrimp keepers?

      Hi I wonder if someone could help with a bit of confusion I have regarding Blue verities of Neocaridina and the gene pool. 
      This is what I have so far and not sure if it correct. 
      1) Black/Chocolate Cherries will produce Blue Diamond. 
       
      2) Blue Diamonds will produce higher grade Blue Cherries 
       
      3) Rili will produce Blue Dreams
      from there I'm not sure where Blue velvets fit in. 
      What type of Rili will give you Blue  Dreams  
      cheers

      Hi guys,
      i'm just curious, how much does each neocaridina shrimp cost in your country?
      i'm in Indonesia, and they are really cheap, i bought 30 red cherry shrimp for about 1 dolar ( 15000 Rupiah )..
      Thank You..

      Indeed a good video. Except for his spelling of Desolved in TDS (should be Dissolved) I could not have done any better.

      Yes of course! Forgot about high Nitrates, and of course illness. But we probably need to clarify "low temps" for anyone new to the hobby. Winter months can see water temps fall below the shrimp's preferred temp range. It might not be detrimental to their health but it does slow their metabolism down. The remedy for low temps isn't to just give them high temps either, it needs to be within their ideal preferred range for that specific shrimp, eg Neo Caridina or Caridina or Sulawesi. I have known some people to have shrimp (cherries) survive our Australian winter out in ponds. So they can tolerate fairly low temps for an extended period.

      Also No3 , low Temp , and bacteria infections.

      This is a very good video on the basics if you are new to shrimps. It is called 'How to breed shrimp', not sure why as it is generally everything and a very good  and clear video guide?.

      I find the wrong water parameters for the type of shrimp to be a big factor for lethargic shrimp. It's usually the first sign that something is not right. Any measurable amount of Ammonia, can also cause this behaviour.  Moulting is also a big factor in shrimps being inactive. Right before and right after the moult they hide and usually don't move. The moulting process is very strenuous on the shrimp, and I find protein rich foods (eg bloodworms) helps a ton.
