Your octopus is being quite normal. He's keeing himself hidden to make sure nothing finds and eats him! He doesn't realize that he's safe now.
Not a bad idea to have a bit of live food in the tank, either.
today is the 4th day ive had him and now he doesnt hide everytime i walk in , but he stays in the same spot , he is eating at night,
i noticed today that there are two emerald crab claws laying on the ground with the rest of the crab missing , so HE IS EATING. which im excited about becasue , i hear some peoples new octos dont eat for two weeks.
im trying to get my sump and everything hooked up asap , and my skimmer
but im n ot really worried about it now as he is young and little, because i had three messy tangs, and 8 other fish in there with no skimmer and my nitrates and everything read 0
I thought the skimmer was going in the sump???will have to re read this bit...
the chances of a full blown crash are small, but better safe than sorry...I have seen tanks larger than yours crash in the space of half an hour, while everyone watched in horror...amazing, really...
it is going in the sump
but I dotn know how to plumb and Im not sure how im going to make my overflows to where he cant get in them, cause i dont have bulid in teeth , they are just glass overflows with nothing on them
so I stuck the skimmer in the tank,
i dont think its that hideous looking
he doesnt seem to mind., plus it puts more oxygen in teh water correct ?
