Im getting a 40-55 gallon tank in 2 weeks and I have recently changed my tank from aggressive to non or semi aggressive. I have an eba, polar blue parrot and a pink convict. Even in the temporary tank I chose to keep the pink convict with my new community tank going up with these guys because he is kinda peaceful. Hes never fought or chased anyone and is nicer than my eba. Will I be able to keep a school of 6-8 rummy nose tetra without having to worry about the tetras? If you have any other ideas let me know, I’m looking for medium schooling fish that has lots of color and won’t cost $10 per fish, thanks!
