Okay. Lets get the basic information out of the way.
-55 gal with 1 severum, 3 angelfish, 1 balloon molly and 4 cories
-water parameters are perfect (tested just now)
I think that's it. Anyway, on to the emergency here. As mentioned above, I have three angelfish. Two of them came as a pair- Sekhmet and Hathor. They have always quarreled a bit, with Hathor being the dominant one, but never have they gone so far before. I've had them since August last year so when I saw them nipping each other on the mouth this morning I thought nothing of it as that's their typical behavior. However, I came home from school today to find Sekhmet completely beat up. Her scales were nipped off, her eyes bit at (they're a bit cloudy), and her fins completely ragged up. I immediately put Hathor in a plastic pitcher to separate her from Sekhmet. Now she's swimming around the tank really slowly, only moving when my severum gets too close. I know that if I let Hathor out of the pitcher she'll go straight for Sekhmet and probably finish her off as she's already really close to dying. I do NOT want to lose any fish obviously so any advice? I have a 2.5 gal cube that I could put Sekhmet in and float in the tank. She would be able to fit and swim around no problem, but is that a good idea? If I really have to, I'll go out and buy another tank, though.
But that's not all. I'll probably have to keep them separate for several days, maybe even weeks, but I'm leaving town tomorrow and won't be back til next Monday. I won't be here to monitor the activity of my fish. I really do not want to come back to a tank full of dead angelfish. Not sure what you guys could do to help me with this one but I could use advice on how to separate the fish and what to treat Sekhmet with. Thanks.
