    Its got a similar body structure as a Black Widow Tetra and its long caudal fin is red. I was thinking they were Pacus

    If need be, I'll separate one and get better photos

    It looks like either like a red phantom or serpae tetras, but difficult to ID with the pic.

    they are definitely not Pacu's

    Look like Serpae Tetras to me.

    They are not predatory, but notorious fin nippers.

    I agree that they look like serpae tetras or Red Phantoms. They're definitely not pacu or a piranha type of fish... (Although, the piranha is related to the neon tetra...)

    A lot of tetras a fin nippers, but I have never heard of them physically eating guppies. Especially not serpae tetras or Red Phantoms. That is absolutely bizarre. What other fish does your friend have in their tank?

    Guppies, a zebra danio and 2 black widow tetras. They've been separated for now though. According to him, they went into a feeding frenzy. He got them from a guy who is notorious for taking terrible care of his fish so is it possible they did that due to starvation?

    It's possible, but very unusual... Just feed them up. Use frozen bloodworm, brine shrimp and good quality flake or pellets. They will be fine in no time. They're actually great community fish. (except with guppies or bettas)

    Ah hah. Exactly like the Serpae Tetras. Now, what can be done about them? I want to see if he'll give me 2 or 3, but only if we can figure out this "feeding issue"

    They need to be fed. If they're killing his fish, and his fish are guppies, then he needs to get rid of either the guppies or the tetras. He has to pick.

    They could also be flame tetras? A better pic would help with a positive ID. Also, it would be best to keep them in a school of fish, and not just 3 or 4...

    Serpae Tetras I had them sometime ago they are terrible fin nippers and will nip any fishes fins they can nip at irrespective of species.
