I have these little mites and I want to nuke them

Recommended Posts

Hello folks,

I have these tiny mite-like critters in my shrimp tank.  They are brown (or white / tan when younger) and about 0.5mm in size.  They move very very slowly and don't know how to swim.  They are also eating up my biofilm / algae/ leaf litter which is food for my shrimp.  I'm willing to evacuate my shrimp for a few days, so what's a good way to nuke them?

Red Water mites or Hydracarina. Not a very common sight in an aquarium.

Anything that would nuke them would be bad to have in the tank for shrimps as well.

If you can move your shrimp to another tank, then drain and dry out the tank to get rid of them. Or add some fish to eat them up.

Remove any filters and ensure none are in there too before adding it to a tank.

Those are creepy creatures?

I had water louse once and I did as JayC says and completely emptied the tank and redid everything, but they were larger so easier to spot and there is always the risk that some may get missed and will re-infest - not seen a recurrence in my tank though, thankfully!

I would probably try the fish route myself though they may also pick off baby shrimplets if they find them! Not sure what the best fish would be though, especially as the mites aren't swimmers so any appropriate fish would be one that goes exactly where the shrimplets are?

Yeah, I don't normally recommend fish with shrimp. But this case it's for a purpose. The smaller the fish the better.

Thanks for the replies.  I don't really want to deal with having fish also, but if so, which one do you suggest?  I briefly looked into microrasbora, but they suggest you buy a school of 8+, and I didn't really want to deal with that.

These don't seem to be the red water mites as they aren't red, nor as large, nor as fast moving, but could very well be one of the many species of water mites.

I think they originally came with my pet store Marimo, so there are probably a bunch still inside anyway.  Thus, I need some way to nuke them without killing the plants.  The shrimp and filter with bacteria I can remove.

I just found a few in the new thank that I set up (almost done cycling), so I will need to nuke them from there also.

You could try some copper based products. I have not tried it on water mites specifically, though.


Just make sure you wash the plants thoroughly before using it with shrimp again.

As JayC states, the dwarf rasboras/danios etc would be my choice, followed by ember tetras or neon tetras, depending what is available to you. I am sure endler guppies (or any other guppy) would do the job but I would also expect they would be more likely to feed on baby shrimps as they went EVERYWHERE in my tank including through/under the moss/mesh at the bottom, behind filters etc, to the point where they have all died out now, all got stuck in various places so am giving up on them reluctantly as they were a personal favourite! They may be worth trying if there isn't anything else but there probably isn't anywhere they won't go to find food (inc shrimplets) is my experience of them? And with guppies you only want all male as they are prolific livebearers? The flip side is that you are probably not going to get over run with shrimps if the fish pick some baby shrimp off???? There again I don't know whether tetras will be confident enough to get to the mites as these fish swim in the open middle of the tank usually??

Adding fish does add extra interest to the tank as well! 

Friends have been here today and brought me some ember tetras and neon tetras for my old fish//cherry shrimp tank, woohoo!

The mites are aquatic Oribatid mites (family Oribatidae).  https://www.mdfrc.org.au/bugguide/display.asp?type=9&class=16&subclass=41&couplet=0

They are slow to reproduce and generally rare in aquaria which suggests that through good tank hygiene the population will decline naturally.  I know you want the biofilm for you shrimp but I suggest clean the glass and clean the filter more often and at least for a few weeks I'd replace leaf material (e.g. mulberry or oak or indian almond) more often so you're removing the old leaves before they have broken down too much and this will remove any mites that are also feeding on them.  Once the mites have gone you can let the tank get a bit dirty again.

My vote is for Endlers. Mine are the most fascinating (from a fish lovers point of view here) and cute fish in my tank, but I reckon they would be perfect for you, as mine are constantly picking on stuff! They’re the only fish who eat my dreaded snail eggs (on the glass and other surfaces) which I love! Plus you don’t need heaps. Males are small if you just want them for this. And you will be able to get them anywhere.

I have a school of 20 embers in my tank, but I rarely see them hunting in any manner, much less on surfaces.

      Thanks for the advice guys, I really appreciate it! As for the details, the tank is my 110L community, and while none of my fish are especially expensive or special, but I don’t want to lose any or have to rescape. The reason I was hoping to avoid qt is bc I don’t have a spare tank or filter atm. I think I will qt I think. How long should I do it for, and do I need to cycle the tank very long?

      Hello folks, This is in regards to my TB tank that has had shrimp for about 2 months now.  The shrimp came in two batches from different vendors - one was two BKK and the other was a bunch of RWP and BB.  Everything was going well for about 2 months with the shrimps actively grazing around and suddenly I found one of the BKK dead and upright in a corner of the tank.  I usually do a check-up on the shrimp every day and the only time the shrimp are inert is one day before and after a molt.  In the past when I had shrimp die for various reasons they would be inert for a few days prior. The water parameters are the same as usual: Amm/NO2/NO3 = 0, ph = 6.0 or a little lower, GH 5, TDS 110 Using RO + SS GH+ and I did a 15% water change 2 days ago, dripping in the new water. I haven't fed any pellet shrimp food for a while because there are still lots of patches of algae in the tank, plus one IAL, plus they finished off a mulberry leaf 2 days ago. Nothing looks odd on the dead body of this shrimp (no real color loss) except the clear parts like antennae and tip of tail are a little orange.  (I think this is typical of shrimp that have died?  Or a molt shell once you remove it from the water and expose it to air.) The only odd things about this shrimp are that in the 2 months, it molted a few times but never grew much (or at all) over the original 1/2" size.  About a month ago, the white parts of it started turning blue.  The other BKK that came at the same time also either hasn't grown at all or maybe just a tiny bit, and only has little patches of blue.  The other batch of shrimp from a different breeder (RWP and BB) have grown significantly over this time. Anyway, the rest of the shrimp seem to still be doing well and actively grazing.  (Actually, two are acting quiet, but it is still within the pre-molt time frame) I hope it's not bacterial infection, but what can I do to prevent / prepare?  I have available: Dr Tim's Eco balance, Doxycycline (fish med), oregano oil, melafix, H2O2.

      I agree with JayC and have N|EVER quarantined personally, but there is also something a little more to consider. My setups are small and simple/basic and don't have many fish  - all about 30L max! If you have spent a lot of time and money setting up a beautiful tank, cycling it etc and then you introduce fish with some sort of disease or parasite you will need to TREAT the tank or may even have to re-setup the tank, if you put those sick fish in it so not only will you lose the fish you may have wasted a lot of time and money, and may have to completely start again from scratch, and never be 100% confident it/they won't recur. You may have to cycle etc again, buy new stuff depending on what the treatment was etc? I would say if you have a small bare bottom tank with a spare filter WHY not quarantine for the peace of mind? I am aware of course that I  am being hypocritical in saying this..............................so just a thought! Simon

      If they are the first inhabitants in a tank, then not needed. Beyond that, it's difficult to answer as it is a personal choice. we never value the quarantine process, until we REALLY need it, by the time we find out, it's too late. And we always wish we had quarantined. If it was me, my thought process goes like this ... i ask myself, do I already have inhabitants in the tank that are so rare and precious that I absolutely CANNOT loose due to disease? If the answer is Yes, than I quarantine any new tank inhabitants - fish or plants.

      Hey all. So, I'm getting some cory cats in the near future, and I want to know if I need to quarantine them. I know a guy at my lfs really well, and I trust the store, so I might be able to get them to hold and quarantine them for me for a week. I'd prefer to just add them straight to the tank if it's possible though. If not, then I can sort a qt tank soon. Thanks in advance
