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!
