I think I disagree with everything on the list except kribs. Even then, a little research will tell you they breed like roaches. I'd replace everything else with: kuhli loaches, cause they hide. Ghost knife, gonna hide. Tiger barbs, gonna nip. Most fancy plecos, gonna hide. Redtail cat, gonna need a pond and still crash your filter. Petco bettas, just straight up support of animal cruelty.
