I used Methylene Blue purchased from aquarium shop . I also sometimes use Iodine !! I would love to buy some proper stains only if someone can tell me where to get those in Mumbai !!

Aquarium water sample

Saw some interesting things when observing an aquarium water sample using the Foldscope.

Not sure if these dead organisms came from fish food or they were born in the aquarium. Can someone please help to identify these !
