appreciate any insight anyone can provide or to suggest another forum where I could post this question
I have a 20 year old florida cooter, she resides in a 120 gallon aquarium, as she has for most of her life. In the past week or so there have accumulated a BUNCH of gnat-like (teeny tiny) bugs that are congregating between the water's surface and the aquarium lid...what's going on here? I just sucked several hundred of them up with the vacuum cleaner! but wondering why they're present in the first place!!!
THANKS
