I bought a blackcap basslet today. He looked exzcellent (shape and color wise) when I released him into the tank (after acclimating.) He bolted for a spot under the LR. I moved a couple of pieces and couldn't find him anywhere. Do these guys hide under the sand? Any ideas where he might be? There's no sign of him outsidethe tank. Any tricks to get them to come out? Thx.
