When talking about "school's" of say tetra's, i'e; "best in school's of at least ten", is it ok for that "school" to be made up of different type's of tetra??
I'm planning on getting a school of cardinal's or rummy nose for my new tank but have some "left over" ( :oops: ) neon's in my smaller tank and was wondering if they would be ok with my planed new fish??
