Aquarium Advice Newbie
I have just introduced 6 danios into a new tank. They are going mad swimming backwards and forwards through the bubbles produced by the aerator - particularly the zebra danios (the other three are pearl danios). They are also swimming around the remainder of the tank. Does this mean they are starved of oxygen and have to swim through the bubbles? They do not look distressed in any way. Thanks for any help.
