K. I have a 29 gal tall, it has a kribensis, a mickey mouse platy, and a green tiger barb. Wanted to add a schol of green barbs but when I got to my LFS..which I love..they get my business...to all of you that use WALMART AND PETCO please stop..your ma and pa LFS needs the business more..and chances are they will be much more helpful w/ better quaility fish. K enough ranting..my LFS only had one green barb, so I got him and 2 other tiger barbs. Now Ive read I should not keep tiger barbs w/ green barbs...comments? I do plan on getting 4 more greens on Sat..they are arriving today and possibly adding more tiger's since I know they like to schol but now I'm not sure they will all get along. I'm thinking since the tigers are more aggresive I wont add any more..just the greens. Thanks for the input.
