Hmmm...cories
i have been using pond rocks that i got in home depot for a while now, i recently read the article about rocks..and i thought to myself, i never really tried to figure out what kinda rocks they were...they are small ish and all over my tank, not the round pebble but mroe like just small rocks, i am considering taking them out if they will affect my tank. Are these rocks generally safe?
