i got 4 tiger barbs 2 were killed by eachother 1 was eaten so i added 5 more down the line. i also had a black ghost knife who was doing fine in the tank for months but was found at the top if the tank torn to shreds not too long ago. anyway someone in the tank is doing some serious nipping and eliminating entire sections of fin in one bite which killed a barb yesterday. anyway my dominant redhump geo has gotten the same section of fin taken off twice in the past 2 weeks. does this look like it couldve been done by a tiger barb? the geo is still relatively small i figured it was the starry night because of how aggressive the geo is but i have reason to believe it was not the starry night. and do you guys think adding more tiger barbs would be the move or just removing them from the tank all together?
