lovely bettas! You'll find Ice will change colour over time. I love the marble gene bettas, you never know what you'll end up with!
one thing i'd like to note though, is the divided little tank you have them in. not a very good setup for a couple reasons: very small water volume, which means lots of ammonia buildup between water changes. also, each betta ends up getting something like 1/4 to 1/2 gallon only each, so very cramped quarters. biggest reason it's not a good setup is that the bettas can constantly see each other, which leads to constant flaring and 'defending territory'. this will stress the bettas out over time.
you'd be better to have them in a 10 gallon divided 3 ways, or in their own separate 2.5 or 5 gallon tanks. if you do the divided 10 gallon, use opaque material for the divider, or use craft mesh with something like java moss tied to it, to break the line of sight.
