I definately wouldn't say its ok to kep TB's with angels. Some people may have had success..but I wouldn't count on duplicating that success too often. Personally, I don't know about rams, and gouramis can be iffy with TB's. I've seen kissing gourami's with TB's with no problems, but I don't know about any other. If you want TB's, stick with other Barbs, most Rasboras, Danios, Swordtails, Cories, Plecos, and loaches. Stay away from Angels, Guppies, some Gouramis, and Bettas. Some cichlids will work with TB's, so do your research on that.
