Iv decided to post on kijiji or usedottawa and trade my 30 gallon for a small beta tank instead makes life so much easier, since we wont have a ton of space at the new place

Just go for a 5-gallon minimum (10 gallons being much easier to maintain). You probably know that already but I figured I'd mention it anyway . Since a lot of tanks labeled for bettas are quite small.

How many gallons does it hold? Try measuring it, there are online calculators .

It's definitely not too big (no tank is going to be "too big" for a betta--they live in rice paddies that can stretch for miles), though. If anything, it's too small.

That would be fine for a single betta then, yup . You'll want some sort of cover, though, bettas are jumpers. If there's no hood (is this one of those new Fluval tanks?), you can use netting or egg crate to make a cover.

I haven't used it but a lot of reef aquarists do. Try searching on Google, you should get lots of info .
