We did defrosted shrimp the first few days, but they seemed to only like stuff inside the head and would leave the body. Not too sure about this as the first few days were pretty much "cross fingers, I hope this works" and they would often hide. Will definitely try again, as grocery shrimp is the most accessible.
We gave scallops a few night nights ago, they refused it. Might have been not hungry, or might have just not liked it. We left 5 live clams in the tank- they've all been eaten. I don't know if the octos opened them up, or if the clams died before the octos consumed them. (I saw one dead and decided to leave it- but when I came back for it later on, it was gone). All of the snails are still alive.
And Seven and Nine swapped personalities, haha. Seven escaped again when we were cleaning the tank last Tuesday. This time he managed to cross the room where he faced off with my cat. Seven won. (Well, there wasn't even fight, the cat just went to look and immediately got freaked out) But after that incident, he's been hiding a lot (but we always catch him peeking!). It's Nine now who comes out more, and is more naughty. He doesn't like it when we leave food for Seven- he grabs the food and tosses it to the other corner of the tank.
They'll be upgrading to a 20gallon soon! Is there really no way they could co-exist in one tank? I'm really hoping they could.
