Star Rider...they are talking about Koi Angels. They are a color form of angels. Not goldfish. As far as keeping angels together in that tank. It might go over well while they are young, but if you get a mating pair, you will probably only be able to keep the 2 that pair up. They will eventually kill the others. They can be kept with all sorts of tetras however. But not neons, they will eat them. Check my sig. My angels arent mature yet, so I will prob end up having to get rid of one of them, but for now everyone gets along okay. I might have to move mr.betta when the angels mature also bc they may start picking on him. I will also have to get rid of one of my rainbow sharks simply bc they will pick on each other. Didnt want you to think you can keep two of them together. Anyway..enough with my rambling.
