I have a 5 gallon FW, with two zebra danios and one otto.
My tank has black sand in it, and I added the fish yesterday, and now there are A LOT of little gray cylindrical things all over the bottom. about 1mm long. I would say it looks like fish poop, but its way way way too much for 3 little fish!!! theres got to be 100-200 of these things lying around..
any clue to what they are?
