ok so currently I have a 10 gallon tank going with tetras cories and a gourami in it. I have been given a 38 and 29 gallon tank. I plan to set up one of the larger tanks transfer my fish over and take my 10 gallon to my 7th grade classroom. My problem is that I am going to be moving in august (same town not far away). I know that I will have to drain almost all the water out (leave just enough to cover the substrate) put the fish and the water in large covered buckets and move the entire operation.
