Hi David,
Strange....I have never heard of something so bizzare. It has to be some sort of insect that came into your house and found your aquarium to be a handy pond to lay it's eggs. This is my best guess that what you are seeing must be a larvae of some sort. If you could give me a better description at all of it that would help now. What is the general shape of the creature? Is is insect like? Wormlike? Please give me a full description of this creature so I can further help you out.

Thank you,
Karen~

Karen, hi, the bug was black, about 3mm long and rounded at both ends, and had silver legs,
Thanks
David

Answer
Hello David,
hmm... This is very strange. I have never heard of such a bug. My first thought was a Dragon fly Larvae but I'm not sure. You might want to do a google image search for dragonfly larvae. You may also be seeing some species of Copepods... This is really hard to figure out without seeing the creature myself. I think you may have to be your own detective in identifying this odd critter.

I'm sorry I don't know anymore than this but I promise I will research it further.

I will get back to you very soon with more info!

Thanks for your patience,
Karen~
