Hey, because I'm getting a Betta I've been doing research on them (and bugging everyone here, like I am now) and I started researching Betta illnesses and stuff. I read something that says you need to get a quarantine tank if you have a tank bigger then 2.5 gals and/or if it shares a tank with other creatures. I'm getting a 3 gal tank (with all the stuff like the filter and gravel it will probably hold 2 gallons or so) but I'm kinda low on funds and don't want to buy a smaller quarantine tank if I don't have to. Do I have to get one? Or will his tank work cause it isn't a shared tank and cause it isn't huge.
