I have a 10 gall tank with 2 glo fish tetras and I wanted to change from fake to real plants. However, I don’t have another tank I can place the fish in so I was wondering if it would be possible to do the change without moving the fish? I also wanted to get a betta fish to add to the 10 gall, but i’m not sure how well it would mix with the glo fish.
