fish compatability

[Nikki_8609]

I have five types of fish in my tank. They are:
Mollies
Guppies
Neon Tetra
Buenos Aires Tetra
Zebra Danio

I also had a Siamese Fighter but it was killed by either the danios or buenos aires, i'm not sure which it was as they were the only ones in the tank at that time.

My problem is that now i have guppies and mollies and one or more of my fish have already killed two of three guppies and eaten off all their fins and their tail that male's have. Can anyone help as to which fish might be causing this. (the buenos aires are now seperated as they killed two danios already)

Please help as i don't know how long the last guppy will last.

How many danios do you have?

(this is relevant I promise)

also...how big is the tank?

what cutlery said and

hi there
sorry to hear of your losses

I would say it either the tetras or danios this depends on how many you have of each.
Zebra danios are very aggressive if not kept in groups of at least 5. most tetra species are the same althought I can't speak for experiance on those.
Zebras will go for any slow moving fish with long fins so your guppies and mollies
are easy targets for them.
I think that you should re-home the danios(to a different tank) or return them to your lfs for an exchange.
good luck with your future fish keeping
