what are some tight schooling fish. ive read that cardinals are and thats why i would like to get some. what are some others???
Rummynose tetras, and Harlequin rasboras are great schoolers. Cardinal tetras school but not a lot, IMO.
Agree 1000%to get a tight school they have to feel threatend...as long as there are no preditors in the tank i really dont think you will have a tight school
