The rainbow pair has established itself behind a rock pile. The tetra swam in and got chased out. It came back again and one of the rainbows swam behind it and grabbed it by the tail fin. The tetra was stuck and the rainbow swam it to the surface. The other 1/2 of the pair came up and started biting the tetras stomach and ripped its pectoral fins off. The rainbow let go of the tail and tore the tetras tail fin up pretty bad. At that point the poor tetra was getting tossed by the current and couldn't right itself. It eventually ended up in the plants and one of the rainbows kept biting it until it was dead.
This took place in like 40 seconds.
