We have a pair of Red Rainbow fish in our tank who are beautiful and peaceful and we decided to get them some friends so we bought 2 madagascan and 2 lustrous Rainbow fish for our very good LFS. we carefully acclimatised them to the tank and they were soon swimming around and eating. woke up this morning to find them all dead but not a mark on them 
. 
Tested the water and the parameters are fine and we haven't had any disease in our tank for absolutely ages.
So that leaves the only answer of MURDER in the Fish tank! My main suspects are above. Note all of these fish behave peacefully except Tinfoil the Angelfish who we have seen murder a molly right in front of us by striking at speed. Killed them in one hit!!
Just wanted to know peoples opinions on this. Should we try more rainbow fish in the future? Could it be something else that i haven't thought of. Your opinions are much appreciated!
Thankyou
