I'm sad to report that I came home tonight and found the tank temp on this cube to be 30 degrees! Darth the black coral goby succumbed to the heat and is no longer with us The bedroom was like a furnace even though the blinds were closed and the air circulation was assisted by a fan.
I think while it's so hot I am going to move the tank down to the kitchen or dismantle it completely, although the latter means if Goby-wan and Ken-obi go into the Osaka tank I am alot less likely to see much of them any more
I've managed to slowly bring the tank temp back down and the prickle face goby and the other two are still alive thankfully, as is my dwarf boxer shrimp.
They'll be cooler in the kitchen as it's north facing. If that fails then I will have no choice but to dismantle it for the time being.
I guess I could do Tina but I don't have anywhere to put it now.
Darth was one of those coral gobies who was notoriously hard to feed and sadly the Force must have left him when the temp shot up. Everyone else is fine and dandy amazingly.
If I take the tank out of the bedroom at least it will be cooler in the kitchen. The occupants would probably love the big tank in all honesty.
