My kribs have rearranged their tank (moved alot of sand) and now my female is held up under a river stone. So I figured she has layed eggs. anyway. can i do a small water change? I looked around but didnt see anything referring to this and wasnt even sure where to post? any help would be great. you should see the mounds of sand these two have made, they didnt like any of the stuff i provided for them apparently. ;)
