I have 3 swordtails. All female. Maureen, Yuki, and Yellow Submarine.
I have 4 Guppies. All Male. Jude, Cheetah, Halloween, and an unnamed guppy.
I got these guppies along with 5 small fish ((Forget what they are called)) and 3 tetras. 2 are large, 1 is small.
Those 3 tetras are biting and nipping at the swordtails and guppies. Maureen looks like she has sustained the most damage. Her dorsal fin has bite marks and pieces missing from the 3 tetras attacking her.
What do i do about these 3 tetras? I know the fins will grow back because my dad had this same problem with his black skirt tetras. What should I do? I have a baby swordtail, Nemo, who is almost big enough to be released. I really dont want to have him get beaten up and killed.
How do i fix this?
