Hi members, I've been approved by the wife to have a new 600l tank! I currently have a 400l with bosemani rainbows, cichlids, loaches, an eel and a bristlenose. I don't want to re-home my fish, just have someone care for them while I get their new tank set up. The location of the 400 is where my new 600 is going to be. I need to shut down my 400 and set up the new tank when it arrives. My problem is I need to "board" my fish babies somewhere. I have no where to put the 400 while I set up the 600 and I need the filter from the old tank for the new one. Any help would be massively appreciated! Michelle
