In that case, you'll just have to do as Matt suggests and remove it manually and wait for it to die down (which it will, in time

Also, Otos tend not to do well in new set ups and need to be in larger groups than two; so another reason for not getting them. If you really like them get a group of 6 in a few months time, but cleaning things in your tank is
