So, im getting a baby betta, and in about a few months, my science teacher is giving out mollies, mickey mouse to be exact, im getting a 5 gallon tank, so im wondering how many i could get into the tank, and if i can even put one mith a betta.
The only true thing I know about Mollies, even Guppies, is that they like to school. You need more than one. Three is optimal. Being that male Betta are solitary most of the time, he won't school with them. Four, three mollies and one betta would probably be my limit for a 5 gallon.
And, that's all really dependent on if your male gets along with them. Some do.. some don't.
Snails are lots of fun and surprisingly fun to watch. A true apple snail would grow too big (some get softball sized O.o), but you could do a mystery snail (I think) a nerite or two, a group of Malaysian trumpet snails, a group if ramshorns, a group of pond snails, or even a rabbit snail.
