It's been a while since I posted here (even read to be honest) but that's what you get when you're keeping fish for a while. anyway. I started up a new tank for an octo a week ago. it's a hexagonal tank of some 250 liters. it's equiped with a sump and large venturi protein skimmer. I'm also gonna install an extra canister filter filled with carbon for supplementary filtration and water movement. the tank is filled with some pieces of spaghetti rock, live rock and some caulerpa. at the moment it houses some shrimps and small fish to keep the filter running. I have to make an octo-proof lid and then it's ready to house a new 8-legged friend. I'll post some pics later this week.
