Well, its in a high school main lobby meeting room. My local store had only tiny bristlenose, probably 1/2 an inch. He'd definetly get either lost in the tank or get immediately eaten by the giant danios. I ended up getting a Rubber Pleco, which I was told grows to a similar size and has very similar behavior. They were closer to 2 in in stock, so I think he'll do much better. Any experience with Rubber Plecos? I did some research and found that they do reach a similar 4-5-6 in max.
