Hi, I have 3 rosy barbs in my 55 gallon. I also have 4 black skirt tetras in a quarentine tank, I want to add 2 more Rosys and 3-5 more black skirts, but I'm wondering if they'll get along. These Rosy barbs are extremely active and "demanding" at feeding time. Will the BST be able to hold their own? Thanks so much.
