I have a pair of young borelli in my 40 gallon and I'm a bit unsure how large they actually reach as adult. My reading is around 2 1/2 inches. I was thinking they might actually fit in a 5 gallon tank comfortably. Is this the case or is that a bit too small. This is my 5 gallon:

Right now it just has a couple of ember tetra and a pile of shrimp. I suppose the borelli might nibble at the shrimp but they have a lot of hiding places.
