hey guys, my Rainbow Shark (young only 4cm) and Block ghost knife (15cm) are like best friends, absaultly amazing, i made a cave in my tank for the black ghost knife (cause there nocturnal) and the rainbow shark was always the inhabiter of it (it was like his territory) but last few days ive noticed him and the black ghost knife in there, they live happily together with each other inside this cave, there almost inseperable, i think this is kind of unusual i dunno about you guys if u have any weird friendship story's of fish, btu yea its awsome, best buddies haha. just thought id let yas know, somthing diffrent.
