3 angels died

[jonny toe tags]

Here's the info.
I've had 2 angels (pair) for about a year now and last week i added 2 more angels.
Now...one of the new ones died, then today i get home, and one of the originals was dead.
Couple hours later, the other original died.
There were no signs of disease.
I can understand maybe one of the new ones dying, but find it odd that the other 2 died within hours of each other.

You say you've had the original pair for a year so I doubt the problem could be an uncycled tank... However, how large is the tank? It may be that suddenly doubling the amount of ammonia/nitrites/nitrates in the tank caused the unusual deaths.
Also, how do you maintain the tank? Do you do partial water changes and how often? Have you changed your filter media recently (don't unless absolutely necessay)? What are your water parameters?
Did you quarantine the new arrivals? They may have already been sick and passed it on to the old ones...
Are there any other fish in the tank? Any other new arrivals?

The tank is a 65 GAL that has been cycled since last august.
I have other fish in there:
3 dwarf gouramis - 3 rams - 6 ottos - 2 siamese algae eaters - 8 Harlequin rasboras - 2 small bala sharks (2") and 1 angel (had 4)
water changes every week. around 30-40%
water parameters have not changed.
No other new arrivals.

That is strange... It sounds like you have a healthy tank and fish... The new one could have died from pH shock but that wouldn't explain the old ones dying. I realy can't think of any other possibilities. Maybe they were just sick and it was coincidence that they died within such a short period of another?

I'm going to stop by the LFS tonight and ask them.
While i'm there i'm going to pick up some more angels, if they have.
