Hey guys! I have a 5 gallon fluval spec aquarium with a halfmoon plakat betta along with a nerite snail. I was thinking of adding some other type of small fish to make the tank more interesting. Specifically ember tetras. I was wondering if I could add in a group of 4 along with my betta?
Honestly I wouldn't recommend it. I would say 10 gallon would be a minimum for keeping a betta with any other fish in the tank. You could probably add some Neocaridina shrimp of a color and variety of your choosing though, provided there is enough hiding places for shrimp fry.
