What type of food do you feed your betta fish? Hikari dried bloodworms and pellet
How often do you feed your betta fish? About once or twice a day
How often do you perform a water change? Weekly, but the tank has not been set up long w/ fish
What percentage of the water do you change when you perform a water change? 15% or so
What type of additives do you add to the water when you perform a water change? I use water that is either from an RO/DI system or from tap water that has been sitting for 24hrs

Symptoms and Treatment
How has your betta fish's appearance changed? Nothing noted from the disease. However, she, like most of the other girls, does have bits of her tail missing.
How has your betta fish's behavior changed? She stops moving, sinks to the bottom, and then does quick darts
When did you start noticing the symptoms? About an hour ago or so. She was normal this morning.
Have you started treating your fish? If so, how? I moved her to a small QT tank with betta revive
Does your fish have any history of being ill? When I got her, her fins were "crumpled up" and kept her fins close to her body. She did not move a whole lot and was in bad conditions. She did, however, get MUCH better before being moved to the DT
How old is your fish (approximately)? I have had her for maybe 1 1/2 wk.
Extra notes: Tank has been up for maybe 4 days and I have had the girls for about 1 1/2-2 wks in QT. One other girl had "something" before entering the DT. Her fins had a clear film on some areas but it cleared up a lot before I moved her to the DT. Earlier this morning, I found the smallest betta dead and half-eaten. I do not know what happened to her. I did a water change after I found her. Almost all the girls had their fins nipped, particularly because of one "bully" who has settled down quite a bit after a time out.
UPDATE: Just after writing this, she died!!!
Ah, I want to save the other girls if there is something wrong. I am so confused! I put her in her QT, added Hikari Betta Revive. She still did the swimming pattern while I was writing but now she's dead. That was so sudden! What's wrong do you think?
Edit 2: I dipped the body in cold, cold water with high salinity. Nothing came out. It's very sad..I felt like I saved her when she healed up. I still have the body if I need to post pics. :(
