i've had my 3 CB bimacs from fishsupply for almost 2 weeks now, and they're doing incredibly well. i also got my lfs two additional that are also doing well...I have all 3 in a 35 hex tank with alot of live rock for them to hide in...For the past 3 or 4 days i've been feeding them crawfish (with their pinchers removed) and finally this morning i saw all 3 at the same time, each eating their own crawfish and I could finally confirm that all 3 are doing well...it's tough to identify which is which when they change shape, size and color...so far there's been no noticeable fighting between bimacs (all from the same brood according to jack at fishsupply)...good news is i'm picking up a 70 hex this week which will become their home in a month or two (i have approx 100-120 lbs of LR curing in a bucket for the past 6 months)...need to get a pump, skimmmer and octo prrof it in the meantime...i'm trying to get the octos used to the net (for when i need to change their home) by feeding them the crawdads from the net...i just love these octos and can't pull myself away from their tank...
