Betta Fish: which of my 3 little communities is y’all’s fav?

first tank is a 10 gallon with a female dumbo betta named iris and she lives with 6 lampeye killifish and some shrimp scattered throughout

second tank is a 5 gallon with a male betta named gus with unique silver coloration and only lives with a mystery snail and a few shrimp (the snail and shrimps are white and red to match gus, so everyone compliments each other in there! it’s also pretty dark in there so they all stand out)

third tank is another 10 gallon with a female koi betta named cleo who lives with 5 pygmy cories, 1 mystery snail, and 1 hillstream loach

all 3 of them are happy, healthy, peaceful, and well behaved!
