...the others, it is a Hydra <"What are these Worms in my Shrimp Tank">. They are easily controllable <"with fenbendazole">, which you can buy cheaply as the Cat / Dog wormer "Panacur". You also have an <"Ostracod in the picture">, these are both harmless and common in shrimp tanks. cheers...

Hi all, It is funny with Ostracod (Seed Shrimps), some fish mainly ignore them, but <"others really like them">. They are known to be browsers on Diatoms <"Ostracods"> (and on other forms of algae). cheers Darrel

Hi all, <"Ostracod">? Cheers Darrel

Yeah, definitely looks like an ostracod. I can't help with the species, I'm afraid. When we find them in samples they are one of the few invert taxa we don't take to species level. Agreed on the flatworm too.

Tks for the feedback Hmmm.. ok …. Just think the little buggers might take over - I have minimal plants coverage (by choice) and lots of white sand so they do stick out a bit when playing around. Cheers Doug Sent from my iPhone using Tapatalk

Those are Octracods perfectly harmless - I have them in my tanks, and an interesting addition to the ecosystem of a tank. Their population seems to rise and fall without intervention. So no siphoning necessary - leave them be 👍

Hi all, Most fish ignore them if there are juicier items on offer, but I kept <"Dicrossus maculatus"> for a while, and they were very enthusiastic Ostracod eaters. cheers Darrel

Hi all, The Ostracods will arrive on their own, they have persistent cysts which blow about in the wind etc. Rainwater and some dead leaves in a bucket should develop a culture, but a small amount of sediment from a pond will definitely get you an inoculum. You can treat them just like Daphnia...

Thanks, I can't find them on ebay myself, looked there before posting. Searched for 'seed shrimp' and 'seed shrimp ostracod'

...food cultures this year. I've kept a daphnia culture going the past 3-4 years quite well but want to try separate cyclops and seed shrimp (ostracod) cultures this summer. Seems like seed shrimp aren't for sale anywhere. I had some by accident a few years ago but they got eaten up fast by my...

Hi all, Entirely harmless, some fish eat them, and they tend to come and go in abundance. They are basically a Daphnia, <"surrounded by a hard carapace">. They are really common in freshwater, even in big puddles. cheers Darrel

Thanks Darrel. So the Planaria need to go I assume - so Panacur at the ready. I can’t find much information on the Ostracods and their desirability or otherwise in an aquarium - I’m all for having as much variety in fauna as possible, so are they a valuable member of the clean up crew, and of...

Hi all, Definitely a Planarian, looks like it might be close to Girardia (Dugesia) tigrina, because of the eye spots. The <"second one is an Ostracod">. cheers Darrel

...that blow about with the dust etc. Cheers Darrel. Interesting article. Although I did laugh though when I read "The number of swimming ostracod individuals was checked daily by visual inspection." I can't even validate my 6 panda corys with visual inspection - they resolutely refuse to...

Thanks, it probably is. The only difference I could see was the single long spiky thing that it looked ad if it was using to dig or bore into stuff.

That looks like an Ostracod. They are harmless. Ostracod on Wiki.

Hi all, No, you are fine, it is definitely an <"Ostracod (Seed shrimp)"> and entirely harmless. Fish parasites are nearly always on fish, so if you see worms or crustaceans in your tank they are very unlikely to be parasites. Predators are free living, so you can get <"Hydra">, <"Damselfly...

Hi all, Yes. Yes probably, moss is a great habitat for small creatures and Ostracods (particularly) are almost <"universal in aquatic habitats">. You may be able to tell from the way they move. Ostracods ("Seed Shrimps") swim smoothly, but in little circles, Copepods (Cyclops etc) swim in a...

Hi all, A lot of fish will eat them, but they are really common in "shrimp only" tanks. They have a number of ways of surviving drought, and form persistent cysts, which can blow about in wind and this allows them to re-colonise small temporary pools. We have a <"number of threads"> about...

thanks for the confirmation Darrel; I did search on here but wasn't too much info. Any ideas about the Otto? Thanks Andrew

Hi all, They are. We have a <"few threads"> about them. cheers Darrel

Hi all, Could be an Ostracod, some of them are very speedy, but it looks a bit big. It is easy to tell if you have the specimen, Ostracods are enclosed in a hinged shell, so they look <"like a bean with legs just showing"> and Crangonyx is much more shrimp like. cheers Darrel

Hi all, They look to be <"Ostracods">, (from <"Aquatoon">). Some fish eat them. I used to have <"Dicrossus maculatus">, and they were very keen on them. cheers Darrel

They are Ostracod aka seed shrimp. Totally harmless and actually beneficial to a planted aquarium. Sent from my iPhone using Tapatalk

Hi all, Try looking for <"Ostracoda">. No and no. cheers Darrel

...male decide to make love and not war with their new tank mates. I've thought many times on what fish I could put in these tanks to keep the ostracod population down but I've yet to find one that would be fair to put in such a small tank, besides I don't mind losing cherries to fish but...

...the Classic Shadow I mentioned in the previous post, the larger CBS next to it is from the previous Generation. Again but with some Ostracods in the shot swarming a piece of Ebi Dama Special for a sense of scale. This would be getting boring taking pictures of the same shrimp were it...

Looking quite lonesome there with only an Ostracod for company, not to worry there plenty more where that one came from. Quite a rainbow clutch from a CBSxCRS, the majority are expressing black colours then reds next, a couple of mottled whites, a pure white and a white wearing a blue waistcoat...

Hi all, Fantastic photos, the thing is an "Ostracod", basically a Daphnia like crustacean with a bivalve shell that it can clamp shut, some fish will eat them, some aren't so keen. I think the "nematode" is a Planaria, you can see a gut etc that a nematode wouldn't have. It is travelling...

...to be settling rather well, and i'm fairly surprised to see them out in the front of the tank. They have been actively hunting the little ostracod's living in my substrate :-), and they have also taken some banana worm. I'll update the journal a little later on and try to get some shots of...

...a tiny species that hangs on the substrate that still appears from nowhere whenever I have a tank without fish in it - a bit like a mini ostracod). Other than that ostracods, cyclops, freshwater limpets and various other microfauna seeded themselves really. Also had less welcome planaria...

Hi all They are Ostracods or "Seed shrimp", basically a Daphnia, enclosed in a shell a bit like a bivalve molluscs <Microscope Image of an Ostracod>. They are entirely harmless, and some fish will eat them. cheers Darrel

Hi all, Ostracods appear in the most unlikely places, I've had them re-appear in trays etc that haven't had water in them for several years. I believe that they can survive as a mixture of "dehydrated juveniles", "encysted adults" and as eggs. Your ones may be the famous Eucypris virens...

Ostracod :) Harmless- I keep Boraras maculatus with RCS and never have observed them attacking the shrimplets. Regards, Dusko
