Oh, and don't forget a good heater. :D For a 5g hex, you can use any of the shorter adjustable 50w on the market, or you can try to find a 25w. Either will work.

And since your tank is a little taller, you might want to try to get a betta hammock or a betta log so your fellow can sleep near the top. :)

If you have any more questions, don't hesitate to ask. :)

Hi fishergirl and welcome to the forum. :)

The Eclipse tanks are good tanks because the filters are very good. The flow might be a little strong but I think you should be able to baffle it, either using a sponge in front or by using a soda bottle. There's a sticky about baffling in the Habitats section. In a 5g with a good filter like that and only one betta, you can change the water maybe 50% a week. But for the first month that you have the tank, you'll want to change the water twice a week, 2 50% a week. This is because it will take a month for the filter to cycle or gather up all the good bacteria.

I really recommend you get a gravel vacuum for your water changes. They make changing the water so easy and it's always very good if you can vacuum the gravel once a week to get the poo and other nasty stuff out.

Usually, you don't need to clean the decorations unless a fish gets sick. Sometimes you have to wipe some algae off but that's about it.
