Is it possible to house a baby cowfish in a 65 g JBJ aquarium? Would it outgrow the aquarium? If so, how long would it take before it would need to be rehoused in a larger aquarium? A worker at my LFS said that a baby cowfish wouldn’t outgrow the aquarium and that it’d fit perfectly. He said that they do grow quite large, but that’s only if you place them in a larger aquarium. Is there any truth to this?
