I usually notice that behavior in stressed bichirs. Trying to hide itself.Thanks. CB or WC doesn't really matter to me, but always a bonus to know. Also is it normal for Endli's to try to bury themselves in the sand? My del's & sen's have never done that, but this guy does. Numerous times today he'll go grab a gulp of air and then when he goes to the bottom he'll try to push his way under the sand.
