I noticed small jellyfish in the aquarium, the size of a match head. Please provide some information about them.

In which aquarium, saltwater or freshwater? Where are they for you, in the water column or on the glass, rocks???

Jellyfish, usually in young aquariums, then disappear. Read about hydroids.

Yes, when I started the nano aquarium, I had such a surge of them, hundreds swimming in schools. It was beautiful, a delight! Since then, I rarely see one swim by... I miss them...
