I am having trouble getting fish that will get along. Right now I have 5 tiger barbs, a pictus cat, pleco, betta, and angel. I will be moving my barbs to another tank as they are eating my angel and now chasing my betta. What else can I put in my 55 gallon? What would work well with the rest of them? I want to get neons but will they be ok with my angel(if he makes it). What about a kissing gourmi? I wouldd like to get another angel but I don't know. I want to have some feedback before I buy any more.
