Beginner Freshwater Aquarium
Hello!
I'm not sure I'm in the good section, to tell everything, I don't know much about fishes, that's why I'm here!
So, I plan on getting a few red bellys piranha's (about 5 or 6) and I've been told that they need a big-enough aquarium, but I'm not sure what size :-? I've heard many things...
