I am moving on december the 1st, I have had some pretty bad luck moving tanks in the past. I have a 100 gallon bow front tank with 25+ africans, 2 29gallon tanks are coming also. only one has water in it right now. its just for breeding guppies for food. and then theres a lil red devil in a 20 and some juvenile aulonocara in another 20G btw the bowfront has an eheim pro 2 big filter on it if this helps. I was thinking of trying to bring 40-50 gallons of tank water to the new house. throwing it in the 100gallon tank, adding another 40 or 50 gallons of new water and just hooking up the eheim with all its bacteria it holds. would this work? for the big tank? and whats the best way to move so many damn fish? I dont care about the guppies btw I was thinking of using 2 temporary tanks, one for the red devil and the other for the africans. hopefully if I can put the africans somewhere in the dark, they will sleep for a while, while I set up...? damn I'm nervous
