I have 2 blue damsels. One of them is taking chunks of sand and moving them away from behind a small rock and then swifting the sand away from the spot too.
DEFAME??? I had one bite the blood out of a friend of mine when she put her hand into the tank to adjust a rock. They are very territorial.
ungrateful little b@sturdz.
here we go giving them free food and relatively little chance of being eaten by a larger fish and they bite us over a rock.
