I just received 4 S. berdmorei from WetSpot this morning. They are approx. 4-4 1/2". The ones I ordered a few months ago were about 2 1/2". Just wanted to let everyone know in case anyone is interested in some that are a nice size. Mine have been acclimated to the tank and have colored up nicely and are out with the other loaches (Y. modesta). I fed the tank some frozen food and they ate well.
