I got a Eclipse 3 >.< and I have a big problem with it overheating :/ if I leave the light on for too long the temperature often rises to 85 degrees F... :S
@Unlimitedx: just so you know, sometimes the filter intake can be dangerous for your betta if the intake is too strong. Bettas aren't great swimmers because of their fancy tail, so sometimes they can hurt themselves when they have to struggle to free themselves from the intake. You can prevent that by taking a sponge and poking a hole in the middle and shoving it over the intake, I do that for all my tanks.
Although I don't know if the Eclipse 3 filter system is that strong, but I always put one there as a safety measure.
xD You'll have a happy betta either way, all my bettas like perching themselves on top of them to rest.
>.> <.< Just my 2 cents. It scared me the first time my betta got sucked up into an intake and had to desperately struggle to get away and ended up tearing his tail )': wouldn't want it to happen to anyone else..
Also your crowntail is GORGEOUS. *v*
