So as I put in another thread I'm going on vacation for 2 weeks. I'm leaving on Sunday 17th. So before I leave I'm going to do water changes and I was planning on using the vacation tabs but am now changing my mind after being told they will cloud the water, bloat/kill the fish. I had bought them for my 25 G tank, 10 G tank, 5 G tank, 2.5 G tank, 2G tank and my 2 fish bowls. 10 g down has my bettas in them. So now I have to rethink my whole vacation plan, and now I have to trust that my brother will look after them. I'm thinking that not cleaning the tanks for 2 weeks should be fine, but I'm really worried about not feeding them. Just wondering what other people do to prepare their tanks before they head off on vacation?
