It Happened Again Today!

[RachelMallory]

So, came home to yet ANOTHER fish with his insides eaten out. This one they left the fins and the eyes.
(If you missed it the other day, I lost a yellow lab in my tank).
This has not ever happened before in my tank and in the last three days there has been two "murders".
So here is my stock:
I now have three venustus (giraffe) africans, one male two females.
three yellow labs (fourth was the first victim).
One blue dolphin
One eye biter
One borleyi
Two firefish peacocks, one male one female.
Two OB's.
and two upside down catfish.

They have had more than enough to eat, I feed them til they get full three to four times a day. Any idea as to what could be going on??

firstly have you listed all your water stats?
how do you no its murder?
if a fish becomes ill the others will see it of
if a fish dies they will eat it

what are your water stats? how long has it been set up ?

EDIT:
im no expert on what to keep with what but here goes
venustus (giraffe) africans, one male two females. SHOULD BE OK
three yellow labs SHOULD BE OK
One blue dolphin SHOULD BE OK
One eye biter SHOULD BE OK BUT I WOULD UP THE NUMBERS
One borleyi SHOULD BE OK BUT I WOULD UP THE NUMBERS
Two firefish peacocks, one male one female.SHOULD BE OK BUT I WOULD UP THE NUMBERS
Two OB's. SHOULD BE OK BUT I WOULD UP THE NUMBERS
and two upside down catfish. MORE OF A TROPICAL THAN A MUMBA CICHLID I wouldn't think the would attack any thing more the other way round

as i said im no expert....

Yes, the UD cats once killed my bubble eye golds. and ripped out there eyes and fins. It could be them.

are you sure you arent overfeeding to the point they die, then they get eaten by the other fish? i had one gutted out not long ago, but i didnt have to clean him out they ate every piece of him. maybe a weakling, nature always selects the strongest.
