my friend's mom's friend had too many guppies that were kept in saltwater. So they decided to take them in without knowing anything! so sense he knows I own a reef tank he asked me if I could take them in. I would but I'm a tad bit concerned. The amount is large and I have a CBS which I believe will take a chance at attacking them one by one. And flow scares me that they can't handle it. So should I take them in? If not I may buy some materials to set up a twenty gallon I have lying around.
