WHO/WHAT IS KILLING ALL MY FISH?!

Hi,

About 3 days ago my gourami died and was full of blood.
( i went out and bought a new gourami)

the next day a tetra died(he looked like he was chewed up and his tail was off)

the next day 2 guppies dies and they also had no tail left...

I have the following fish

1 gourami (got him 2 days ago)
1 guppy left
5 neon tetras
3 blood fin tetras
1 candy tetra

and I have a 20 gal. tank...
HELP!

has the tank been cycled properly? if not then id say the fish died from high ammonia levels and had their fins chewed on after they were dead, read about cycling and the nitrogen cycle, there is an article on this site under articles

Well none of those fish are predatory so Im not sure if it would be the fish. Maybe they are getting sucked into the filter? But it cant be any of the fish they are all peaceful community fish.

maybe it is some kind of internal infection... was the blood in streaks on the body? Try treating the tank with Maracyn Two.
