Hi hope you can help.
We've had our aquarium tank now for 9 months and got three angels about 7 months ago. One died after a few weeks - he was a bit of a runt to be honest. The other two flourished and grew to the same size. They have been the best of friends until a few minutes ago - one just suddenly started attacking the other. The victim looks rather poorly but we're not sure whether it's because he's been getting attacked by the other, or whether he has some sort of disease, hence why the other is attacking - maybe he smells different because he's ill and the other doesn't like this? His fins and scales are battered and he has a cloudy eye. Did and water test and all fine. All other fish are great. Tank is 120 litres.
We've put the victim in a hospital tank and the attacker seems to have calmed down and not attacking any other fish. Any thoughts? Help!
