I picked up a couple dwarf gaurami this weekend and a couple opaline gaurami. My dwarfs seemed to be only slightly bothered by my betta that harrassed 1 of them and have proceeded to swim about the whole tank, but my opalines seem to just hide in the upper part of my tank behind the filter unless it's feeding time. Is this just due to the new tank or are opies more timid in general? Would adding a few more opies help out? Thanks! *BOUNCINGS
