It means that you'll be getting a fish that would be 1-1.4 inch fish and that they do well with other fish. What I was saying is that they fight with their own kind. Otherwise they are okay with other fish but still, the environmental requirements for it to be happy is way off.
I mean, you're more than welcome to get one if you have room, they do grow to 4 inches and they eat most algae's I believe but like all algae eaters they do poop a lot. They're a lot like a BN Pleco
just cuter ^_^
