As I was staring at my molly fry I became focused on this thing attached to my aquarium glass. Theres a couple of them but not too much. All just maybe 3mm in size. Nope, don't think its a bug but its definetly some kinda organism growing on my glass. Doubt it would be harmful to my fish cuz its not moving but just wanted to find out. I do water changes twice a week 30-50%. Kinda hard to describe so i did a little drawing.

water hydra I am sure, Dont know much about them but someone may have a diff perspective
 
probably hydra. Hydra prey on small crustaceans, worms, insect larvae or fry. Therefore they are usually associated with tanks raising fry. They are capable of killing fry from 10 to 15mm (0.4"-0.6"). Larger fry that are trapped but manage to escape will most likely die anyway, as an after affect of the Hydras stinging cells. Tanks that feed a lot of live brine shrimp can attract Hydra as well. there are three products that can be used to remove them. Dactycid, Flubenol and Panacur. To reduce and hopefully eliminate Hydra numbers, water quality should be in top condition, and feeding should be reduced. salt is also useful for the erradication of hydra at 0.3-0.5 % for five days.
