I just introduced 6 blue botias into my 75g tank yesterday.  Now, to my utter dismay, I noticed that my beta has had his fins decimated.  Other residents of this tank include cardinal  and silver-tipped tetras, rummynoses,  bala sharks and  long-finned  blue danios.  I had expected trouble for my beta with the silver-tips, but things seemed to be going well.  Is it possible that the botias wreaked this havoc last night?  They seem to be awfully timid fish.  I am sure that my beta was fine before. If anyone went too near him, he bluffed them off. Never see anyone chasing him. Will his glorious fins grow back?  Help!
