I currently have 7 tanks up and running with my 260 being delivered on the 29th of this month. I feel that I just don't have time to enjoy them all and it has become stressfull maintaining them all, most just have food dropped in and a water change weekly without me every really paying any attention to the fish. I've decided that once I have my 260 up and running i'm going to sell off every other tank apart from my betta tank (had this little guy for a couple of years now) and focus on the 260. I remember how much I enjoyed having just my 90, would always be messing around with it, water changes every couple of days etc and could sit back and watch it for ages. I really can't wait to sell off all of my other tanks and enjoy fishkeeping properly again
