Hi guys, long time no see!
I came home with a new cave for my newest fish, who had gotten himself in some unfortunate trouble getting trapped under his other cave for several days...then doing it again after being rescued. I moved the older cave into my divided tank to the center of three segments. When I was putting the cave in I did brush against the divider while trying to avoid breaking his new bubble nest, but it didn't feel any different than other times I've brushed against it so I ignored it. I went and did some things somewhere. I was sitting on the couch when I looked over to my fish tank, and noticed a flash of yellow in the center segment. The fish living in the center was purple. I tore the lid off and saw Mocha and Cappuccino having at it in the center. No time to waste, and my scoop in the other room I did the only thing I could think of; I cupped my hands and picked up my fish with some water and tossed him on the other side of the broken divider to buy some time to get the cups ready. I took all three fish from the tank to do a damage evaluation. The divider can be fixed. Espresso, the third fish, was fine. Cappuccino, my yellow fish, was swimming in circles but seemed unharmed.
Mocha is torn to shreds. His beautiful fins that I worked so hard to repair when I first got him are torn up, some pieces were in the tank still. His left fin is mostly gone and he isn't moving it. His right eye is swollen badly. He doesn't seem lethargic but he is very pale.
I have moved him to a half gallon bowl, with large rocks. He has a heater and the water temp is 80 F, and I have put in a small amount of aquarium salt. I plan to hold off on feeding for 2 days if he manages to survive the night.
I also moved the other fish involved into a quarantine tank, but he seems to be quite lively.
Here is the question sheet now.
