Hi, I've had a nano tank for a year and love it but find myself wanting to buy more exotic fish and coral. I'm looking to buy a bigger tank but have some specs I am looking for as well. I'm looking for a tank that is large enough for multiple larger fish, but I can still maintain myself as far as having the right equipment and keeping clean. I also am not looking to take up a huge area of the house (considering my wife doesn't want a huge tank ). Are there any suggestions on tanks around maybe 60 gallons that anyone has? What size would you recommend? Would an AIO be the best option? Thanks!
