I found a rock covered and I decided to put it in my tank. but I did put it in a jar of water for 2 days. when it came time to put it in, there was a strange yellow/black beetle that would crawl on the bottom in the water. I threw him in anyway. now 2 weeks later hes still in the tank, still underwater. my shrimp won't eat him but, what is he? he doesn't swim, he can't even climb glass. he just crawls around the bottom. he's less than a milimeter.

ALWAYS BOIL AND SCRUB ROCKS BEFORE PUTTING THEM IN YOUR AQUARIUM

Ummm....I think he just wants to know what kind of beetle it is. Sorry, I have no clue. You could try googling it to see what you come up with.

Does it look like this:


I found it here: http://www.zin.ru/animalia/coleoptera/eng/biol75.htm
Here is a quote from that site (yikes! Shocked )
Quote:
The majority of aquatic beetles are predators on other invertebrates, mostly insects, crustaceans, molluscs and oligochaetes, although some may attack tadpoles and alevins of fishes or consume eggs of fishes and amphibians. Larvae mostly actively attack their prey and seldom feed on fungi and plants only, adults are quite frequently scavengers or are mostly phytophagous.

Hope this helps!

How about this cute little fellow:


Tiny beetles similar to those are very common in Southern Ontario freshwater ponds. Not sure about where you are. Anywhere from the size of a pinhead to about... 3 mm, maybe?

And there are definitely freshwater aquatic mites of many different colours.

Awesome! Hardy little critters. We often bring them into the nature centre to be part of our pond life displays. We call them "crawling water beetles" but I'm pretty sure that's not scientific...

I believe they're scavengers, likely to clean up dead plant matter in your tank and unlikely to do any other harm.
