There is a hippo tang at my lfs that I'd like to get but he is a little dull in color. He seems to be healthy and he ate well, I'm just a little concerned because his color isn't very bright. The lfs said he will get more color once he is in a more stable environment, is this true? I'm wondering if I should buy him or just wait for their next shipment to see if there are any more colorful ones.
