SUMMARY

The discussion centers on identifying a microscopic organism collected from a fish tank, likely belonging to the group of protozoans. Participants suggest that the organism may be Lepadella patella, based on its observable characteristics such as two flagella and a distinct oval body shape. Staining techniques using saffronin and methylene blue were employed to enhance visibility, although the organism remained somewhat transparent. Accurate identification requires proper staining and magnification details for clearer observation.

PREREQUISITES
  • Basic understanding of microscopy techniques
  • Familiarity with protozoan classification
  • Knowledge of staining methods, specifically saffronin and methylene blue
  • Experience with identifying organisms under a microscope
NEXT STEPS
  • Research the characteristics and classification of Lepadella patella
  • Learn advanced microscopy techniques for better specimen visualization
  • Study the effects of different staining methods on microscopic organisms
  • Explore the life cycle and habitat of Apicomplexa and other protozoans
USEFUL FOR

This discussion is beneficial for microbiologists, aquarists, and anyone interested in the identification and study of microscopic aquatic organisms.

Does anyone know what this is?
I took the photos using a digital camera through the eyepiece of microscope.
I collected the specimen from my fish tank :rolleyes:

These are likely to be protozoan or microscopic animals. In the first two picture, the organisms seems to have a flagella but it is hard to says without the proper stainning.

It is hard to do any identification without the proper information and equipment.
 
Apicomplexa plasmodium?

Or Paramecium in conjugation

Chound you got some nice pics, but yeah you need to stain these things you see under the microscope. Get more pics.

I did stain them using saffronin and methylene blue(That's all I've got). But still they are transparent. I am pretty sure they have flagella.

The second one looks like some kind of organism(has flagella) with spores inside it.
 
Better picture

I think this picture seems to give a better idea of the organism
Here is the things i could obsere:
1)2 flagella which join inside the body.
2)Almost oval body but the front is modified like the horns on the devil.
3)I think it has a nucleus near the left devil's horn
