Since I have a 55 gallon tank in my room and my brother really enjoys it my parents are thinking of getting him a 20 gallon long aquarium
Since I have old filter carriages can I just put the old ones in his tank and have them float since they would be too big for his filter?
Also would zebra danios be ok for the tank
