Lately i have seen on 2 occassions very small minute insects in my Leo's tank.(As small as a piece of dust) What are these and are they harmfull to her? I regularly clean her tank and always remove her pooh. Her appetite is still as strong as ever but i am concerned about these little guys in there. My tank is at the window so could these insects be from outside or is there something more sinister going on in my tank. I use tile for subtrate and i have a collection of wood and plastic ornaments in there.




. It's just a concern one should be aware of.
