I have a (I think) a 3 gallon tank and have a betta fish and a snail. Recently had 4 ghost shrimp in the tank. I'm assuming they died or my betta ate them, a few days later I find these little white specks all over the top of the water and now have little white things on the glass and swimming around throughout the tank. Thought maybe baby shrimp but not certain. Any ideas I cant get very good pictures but could possibly be copepods as well but how would I get those?
