Re: Mounting needle
A biology dissection kit has some nice tools. There are a few of them on Amazon. And not too pricey. I got this one. It is working well for me: https://www.amazon.com/Anatomy-Biology-Dissection-Scalpel-Blades/dp/B07DH9MDS3/ref=sr_1_1_sspa?ie=UTF8&qid=1546026764&sr=8-1-spons&keywords=biology+dissecti...

Thank you I was up most of the night finding distinct critters. Look like I also found a leech or two. I am new to microscopy and have a very limited vocabulary.

What are some of the most popular stains (please include wet mount media also)used in Microscopy?
I am taking a poll on the most commonly used stains in microscopy. I'll summarize after a few posts. Popular Science has a similar article -- that might need to be revisited. Here is what I have on my list including wet mount media: 1) Bismarck Brown Y 2) Eosin Y 3) India Ink 4) Iodine Solution 5) J...

Just wondering about what is happening. I place a drop of Iodine on a fungus (I think sclerotia) and the iodine drop appears to be clearing and the fungus is absorbing a colour. Is this some sort of a cation exchange? The iodine drop beads but something is being pulled out of the iodine. Tried a few...

A Large Something Or Other In The Vermicompost Tea!
A critter in vermicompost tea after 8 days of aeration. Is it a Red Wiggler earthworm (Eisenia fetida) or a Nematode? From previous observations when I aerated I saw that Red Wigglers die off and float to the top then sink. I do not think a red wiggler can survive in compost tea. So do not think it ...

Posting the links will do. Facebook messes (scales, crops and compresses) with uploaded images. Google photos seems to handle large file sizes and image dimensions well. I'll start using Google more for lossless images.

Re: Vermicompost tea after 8 days of aeration.
Even at 40x with no well slide, the organisms are just shadows shooting around.
What kind to the medium can they be mounted in that will dry with no air bubbles?
Would something like glycerol work?
Or just let them dry on a slide without a coverslip then apply coverslip after drop dries?

Vermicompost tea after 8 days of aeration.
At 20X, a 40X Objective bends the coverslip on a concave slide.
Looks like a nematode survived 8 days of aeration at 15° to 20° c temperature.
Very small critters in there!
