Howdy from Texas, Just Kidding we don't all speak that way. To the point. I am an intermediate saltwater hobbyist. I currently have a 110 gallon reef tank and have just acquired a 75 gallon tank from a fellow club member. It is drilled but has no overflow presently. I thought of making this a FOWLR tank but, I have been bitten by the Ceph bug again. I first attempted to keep an octo in college with some success but, after a couple of semesters or so it passed away. I do not know which type it was only that it was sold to mE as an atlantic pygmy octo. Which took forever to get from the LFS. I was thinking of making a calfo style overflow with careful attention to escape routes but, my questions start with: * what type of waterflow should I plan for, *Is there a benefit in running a fuge on the system * is southdown an acceptable substrate with maybe so carib sea floor or puka shells. I already have plenty of live rock which I can transplant to the tank from my 110 so that is not a concern. Finally in acquiring the animal if it is a bad idea to have more than one why does octopets have the option to sell them in groups of two or three. If that is the case why couldn't I partition my tank in half and buy two. Would I have a chance at successfully mating the specimens? I am sure that this is pretty difficult but, I just had to pose the question. Thanks! Plenty more question will follow.
