om...
I purchased an fully grown (6") angel today and added it to my 55g
tank. Within an hour, another smaller angel (4"), had shredded my new
angel. The new angel didn't even fight back. I have a third angel
(3") that was fine and didn't do a thing. In a panic, I put the
agressive angel in a 5g bucket with an aerator and heater. The new
angel looks like it is doing better, but we'll see if it survives the
night. What should I do? Thanks in advance. -Matt

55g setup: (running approx 1 year)
fake plants, moderately planted
3 plastic caves/tree stump

2 Clown Loaches (3" each)
1 cory
1 blue ram
3 angelfish (3", 4", and 6" including the new one)
1 pleco (5-6")
6 white clouds

Some guidelines:
1) Quarantine new fish. Even if they are free of disease, it gives them
a chance to recover quietly from transit, acclimate to your water
conditions, build their strength up and you can be confident that they
are eating properly.

2) Respect the limitations involved when mixing territorial fish,
especially as adults. It very often can not be done.

There is no sure-fire solution. In theory, tanks are stocked in the
order of smallest least aggressive fish to largest territorial fish last
(however all should be juveniles). In your case, you might let the 6"
Angel acclimate for 4-6 weeks in your 55g, and then re-introduce the 4"
and watch the fireworks fly. There is a slim chance they will
co-habitate. Re-arranging the interior with new plants, driftwood etc
will help. Adding in other fish sometimes helps distract two aggressors
from getting too intense with each other. jmo
