I am looking at the possibilty of setting up a species tank in my living room and welcome any advice. This tank would be for seahorses and maybe a pipefish, with some LR and maybe some soft corals/zoos. This tank would be an extension off of my 180g reef/sump in basement, so in terms of equipment needed I am thinking just tank,light and maybe heater. Not sure of what tank to pick, but I have heard horses like tall tanks. I am thinking maybe a 29g w/ overflow but have not found one yet. Any advice ? Thanks
