I have a very successful heavily planted 10 gallon aquarium with a dozen neon tetras, cherry shrimp and several otos for about 8 months now and everything is doing very well, in fact the plants are almost doing too well by taking over the tank.
I want to move everything to a 20 gallon tank. I would like to know if there is a way to do this without having to go through the usual major break in period if I were to transfer the water, plants, filter and all to a larger tank. I suppose I would have to use some new substrate.
Can anyone tell me how to do this in the least disruptive way to my fish and shrimp?
