I swear these fish are going to drive me INSANE.
A while ago I had a problem with Ami's fins being torn up, I decided it was from the plants & had her out of the tank for probably a month. I also had to take Zetta out of the tank because she was missing scales on her stomach, not sure why, but they are growing back.
Thursday night I reintroduced Ami. All of my girls are peaceful except for Drina & sometimes Ami. Drina can tend to be a little nippy & sometimes Ami flares her fins. They are obviously the two top girls.
Drina was being a major you-know-what so I had to take her out; Ami, Delta & Vegas were all doing great!
Tonight I look in my tank & Delta's fins are shredded & she isn't swimming.

They were a little torn earlier, along with Ami's but I hadn't seen any fighting or chasing. Delta is now in a hospital tank, Ami is floating in a cup, & nice little Vegas gets the whole tank to herself!
All of the plants (minus 2 small silk ones & 1 real one) are plastic. I didn't think that I'd have problems with them because they are all really soft & I don't see how a plant could do this kind of damage to Delta's fins. But I have a couple of the same plants in two of my males' tanks (neither of their fins have EVER been torn).
Is this fighting that I am just not seeing or is this my plants?
