Thanks Peter, As usual, appreciate your response.
1) I guess 40cm or about 1.3 feet is probably the widest i can go for. It woudl be something i have to live with.
2) Can i do without Chiller or Fan? The reason is Chiller will increase my electricity bill noticeably and fan will increase the noise noticeably. I need to lie low, to avoid my wife realising that there is a new tank at home.
You can do without chiller and fan but you will probably be quite restricted in your choice of corals. As mentioned, you can try with zoas and mushrooms first. Previously for my 2ft tank when I was running it without a chiller, I kept brains, pratas, acans, zoas and mushrooms without any issues.
3) if without chiller or fan, I cannot keep the water to 28 degrees, would room temperature be bad for the fishes? I would like to have them in my living room, but i don't want them to have to die for me. If need be, i'll stick to FOWLR and be contented.
Fishes can survive in room temp water but will be stressed. Again depends on what type of fishes. Clowns or nemos will probably do fine as will gobies. To reduce the temp of the water, you can freeze a bottle of water and dump it in your tank.
Sorry for really dumb questions.. i kept FW tank for many years, but marine tank, this is going to be my first venture... and it cannot fail, otherwise, my wife will notice the new tank at home.
Ha ha
cheers,
