What Is Killing My Fish?

[Charlie123]

i have a fish that has killed a guppy and a platy and some other fish, please could you tell me what it is if I name my fish Today I bought a firemouth cichlid and a siamese fighter so I don't want those to be killed.
I have:
2 Harlequins
2 Silver Dollars
1 Guppy
2 Red tailed black sharks
1 Angel fish
1 Clown Loach
1 Pakastani Loach
1 Pleco
Also what can do to stop it killing my fish?

sharks angels, silver dollars, fighting fish, and the firemouth are the murders, and also, to be honest i would fix tht stocking if i were you as those fish are likely to die from stress very soon, dont be suprised if you find another dead guppy

No because I only got the fighter, the firemouth, the silver dollars today and I know its not the sharks cos I had them in a seperate tank when the guppy died so is it the angel?

 

[Fishy friend2]

stress, ammonia, other toxic substances, and the angel fish are all factors

how big is the tank?

I don't know how many gallons but I know its 120 cm by 50cm by 40cm and well then its the angel fish, because my dad has worked in shops before and told me the waterquality and everything is all fine

It will take a tougher fish than anything you Already have to kill a firemouth ..
If I were you I'd be testing your water.

Nothing has killed a fire mouth? and no the guppys fin got nipped

 

[Fishy friend2]

60 gallon

 

[Charlie123]

What has been nipping the guppys?

 

[Fishy friend2]

harlequins because of unacceptable group size
