Cleaning betta tank

[Tempestuousfury]

I've got a dual betta hex tank for my two bettas. It's rather small, but apparently it's big enough for the bettas I have in it.

How would I clean this "tank" out? How often?

I had single hexes. I siphoned out the dirt and about 35% of the water every 3rd day using a turkey baster. Some might say it's not often enough, but I had to give a chance for StressZyme to work.

All right. Thanks. Now to get a turkey baster or a substitute...
Darn emoticons, can't get the one I want...

Yup ,a turkey baster is the betta keepers best friend

I recently purchased an azoo mini filter...I use that for water changes now (alongside the baster of course). I just hook up the filter to each betta tank and let it run for 10-15 minutes (while each betta has a tantrum) then I do a 50% change. I love that thing

Where would I get a filter like that. (Removable)?

Side comments:
I'm going to guess that picture under your name is your betta. It looks beautiful!
I've got a black one w/ red tail and fins and a light blue w/ purple, red, and green. The latter never flares or stretches his fins, and the former looks beautiful when he flares, but his fins are never as large as the one in the picture.

Will they look anything like yours after some attention and specialized care?
