Well, petsmart is having a sale until june 20th, and otos and harlequin rasboras are only 1 dollar each, but the neon tetras are still the same price. Once I finish cycling my tank (hopefully before the sale ends) I'm definately going to get either the harlequins or the tetras to be tankmates with my betta and I need to make up my mind. Not counting the price, which one do you think is better and why?
