Ok i have to admit that i am new to sea horses, but i have been keep reef tanks for a little over 2 years. Well what i was thinking was could i attach another tank to my 75 aggressive, and by attach i mean plumb together, to keep these slow but admazing creatures? What size would be a good tank? If i do so it would be plumbed into a 75E with a 30 gal sump. I would only put tank raised SH in it. I know that tall tanks work better than shallow tanks. Any help would be greatly appreciated. Thanks. Ben
