I have a female platy who I've had for over a year now (She's actually the one in my profile picture). She is in a 20 gallon tall tank with a few other femal platies, 4 glofish tetras, 2 zebra danios, and 4 ember tetras. This might seem irrelevant, but I have a blue glofish, an orange one, a purpley one, and a yellow one. I inherited the blue one from a friend who was keeping it in a 2 gallon tank with 2 glofish danios 
I decided to get it a little school which consited of a few more glofish tetras from my lfs (I don't remember the exact number as it was quite awhile ago, but i want to say it was maybe 2 more). I got these fish while I had the female platy in my tank. One of the new fish I had gotten was a yellow glofish tetra. It was doing all right until one day I noticed it had shredded fins. At the time I contributed it to the blue glofish, who seemed to be at the top of the hiearchy. Then one day I came home and noticed the yellow glofish was missing an eye. He actually did ok for a surprising amount of time, before he stopped eating and I put him down. I then got a few more glofish tetras, which included another yellow one. I had noticed he had shredded fins after being in my tank for a while and I just decided to let them be and see what happened. They actually healed up quite nicely, but a few days, I noticed his fins were shredded again. I noticed that none of my other tetras ever have shredded or ripped fins so I contributed it to the dominant blue glofish again. But today I decided to sit down and watch my fish for a bit and I noticedmy female platy nipping the fins of this poor yellow glofish. So I think she's the one taking out my yellow glofish (Maybe a little of a combined effort with the dominant blue glofish, but I have seen her nip the fins of this fish multiple times now). My theory is that maybe she thinks its a plant because the fish is a neon yellow which might look kind of green? I'm not entirely sure, but I've come to the conclusion to start feeding my fish more that my platy will stop going after this fish thinking it might be food. I do 15-25% water changes every week. If anyone has any suggestions on what I should do from here, I would be grateful. Thanks!
