Ok because my last thread got confusing so I'm going to repost. I currently have 9 panda cories, 9 gold barbs, 6 otos, 6 small ramshorn snails, 5 ghost shrimp, 4 neons, 3 tetras, 2 striped Raphael catfish some fissiden s. Java moss and some kind of upright plant with white sand as substrate. All are in my 30g. I was wondering if I should move all of them into my empty 75g which has really nothing but water, filters, heaters, and the white sand substrate. And what I should stock the tank with if I were to move the inhabitants from the 30 into the 75.
