I am beginning to feel un-needed (but I am still going to watch!) .DinoIgnacio;129815 said:I highly recommend the Cephalopods book by Nancy and Colin. http://icanhaz.com/cephalopods
It's great and informative reading cover to cover! It covers everything you need to know about the more popular breeds of octopodes.
Mercs don't grow too big, they have an average mantel size of 1.75 inches. and have 2-3 inch arms.
You probably want a small LED lamp as the red lamps that are used for reptiles generate heat. Your octo will prefer a temperature of the lower 70s. I use one of these http://www.petdiscounters.com/Marina-Micro-LED-Aquarium-Light-Red-p7280.html
But after reading what D wrote, I think I will try red vellum over my other lights as well.
We found that the velum will work when placed directly over the transparent cover if it will completely block the white light (aquarium and lighting setup are a big dependency). Be sure you use a velum that is rated for high temperatures (like the kind rated for tail lights in temporary automobile repairs - remember I am from the south ...). I found a good vendor on eBay if you don't find it locally.
Our two new members acquired their mercs from a fellow TONMO member, Danthemarineman. I believe the mercs are by-catch from the cultivated live rock where he works.

The drop down provides the option to send a message via email to be able to contact him directly.
