Parasite

[soupa2]

hi all, i just gotten an amoeba off my Arowana. it was attached to the bottom anal fin. toward the tip of the aro. i notices it few days ago and for three days it have grown to the point that i know it's a parasite. so the other days i try to catch the aro and try to operate on the part where the parasite was festing on but i guess the aro was flicking the water so much that the bug like parasite came off. i manage to catch it with my fish net. i then put it into a small bucket with a feeder hoping that it was feed off the feeder but it didn't so would someone tell me what it is. i have taken 3 pics of it..the tank consist of 3 parrot ciclids, 3 motoro rays, an arowana, 3 datnoids, and a Fly River Turtle..
here is the pics.

Amoeba cannot be seen unless you have a microscope. They're single-celled animals. Your pic shows Argulus better known as fish lice. You should have destroyed that parasite. No fish will eat them.

under what condition does it get into my tank? the feeders that i feed or from where?? how to kill it if you can get it off my fish?

I think I've seen it on some of the goldfishes I had when I was a kid.
You can put some table salt on it and that will kill it very quickly. give it a try.

it was a youngling so i died when i took it off my aro's fin.

Yes, as Lupin said. It's fish lice. They're probably from the feeder fish you buy as it's been with me. Find some anti-parasite solution to get rid of them.
