Hi everyone. Currently, I have a 20 gallon aquarium and a 10 gallon one. I have goldfish and danios in my 20 and some swordtails, guppies, and neons in my 10. I want to change my 10 gallon one to a 20 so I can have two 20. What would be the easiest way of doing this? I was thinking of getting a divider for my 20 just so I can put my 10 gallon fish in there. I thought that they could live in there for a week or however long they should need to be in there. What do you guys think? Thanks.
