I am currently looking for a nice big tank for a Jag and maybe a few other monsters as tankmates. I am stuck on the 18 inches wide footprint of the the 75-150 gallon tanks. Is that wide enough for a large jaguar to turn around and be comfortable in? Like is a 120 or 135 big enough? Or should i go for like a 180 because its 24 inches wide? Ive never had a Jag before but I am really ready to get one so any input would be appreciated.
