Hello! So, I have just been gifted a 40-gallon tank with a stand. I am unsure of the dimensions as of yet since I have to go pick it up at my sister in law's parent's house. I was just wondering what would be a good stocking Idea. It's funny how fast I went from no tanks to plenty of tanks lol! I currently have two 10 gallon tanks. One is a grow out tank for my 3-inch axolotl, I was planning on buying a 20 long for him soon. The other holds 3 tiger barbs. I was thinking of switching one or the other to the 40 gallons. If I switch my axie over....the tank must hold only my axie and maybe a future axie. However, I also know my barbs would be very happy in the 40 gallons as I was thinking of bringing them back to the shop since my 10 gallon is not suitable (I did not know this when I got them). Not sure what to do. I could just move the fish and buy the 20 long for my axie.....what would be a good pairing for the barbs?
