DO NOT PUT AN ALGAE EATER IN WITH THE BETTA. The betta like to have their own territory. If you put another fish in the tank with it, the betta will fight it. Sorry but I don't know much more. My bro just got a betta a couple weeks ago and they don't need alot of space and a good thing to have in there is a plant. Not the fake ones.

(Let me know if my advice helps )
