congo tetras get 2/3 inch? pear gouramis can reach the 5 inch aswell? thats about the biggest size i would normally recommend in a 50inch tank.Ok. I heard you can’t really sex kissing gouramis, but I don’t want to spend 80 bucks on Congo tetras and they get eaten. I do like Congo tetras. I like pearl gouramis but looking for something with a little more size. I don’t know, just looking for a 6 - 12 inch peaceful and colorful fish
12 inch fish dont fit in your tank. thats a 3 times there body lenght tank. And 18inch is also not a very nice size for a 12 inch fish to turn.
