I was thinking of putting schooling fish in the tank since the tank is small. Thats what i was thinking of. My 30 gal has lots of charicins in it of diffrent species. But over the years i am gonna be changing that tank to like a big schooling tank full of colorful fish. I have a upcomming 55 gallon im gonna buy in 3 months. and i have no clue what im gonna put in it. Im still thinking what im gonna do with that tank or the 55. I also have a 5 gallon tank that has nothing in it and i don't know waht i am gonna put in that either, i know it's my choice what im gonna put in it. but i need some ideas soo i came make it better tank than how i used to set my old tanks. So thats why im asking.
