For me it’s 6 or more otocinclus, 6 or more corydoras Habrosus, 2 or more Amano shrimp, Nerite/bladder snails. This is the ideal clean up crew for me. Definitely need a decently sized tank to keep all of them healthy and happy. Therefore, at least a 20 gallons long with medium planted tank so that you can add in a few other fishes that you want.
