Roy - I did read up about that! But I had used it before on Dumbo when I first got him, and I only use 1 or 2 drops for the whole 3 gallons setup. It just helps it heal a little bit more. Thank you for your concern though! I just don't have anything else on hand right now.
Tokala - he is loving it! If bettas eyes could light up and glow, his would have been neon! He was and is very happy. Has anyone ever taken a step back and looked at how much water 3 gallons is? It's a ton! :D He loves it. My room is extremely warm, we don't exactly have spring here. Summer forever! Bleh. So the temp is good. :) I hope his fin rot gets better too! With all of my heart. Haha, wow, yes the marbles really do match him! :)
Johnificent - thank you! I know, it's kinda boring, but he does look good in it! And I love the colorful new plant too.
