Some of you may remember me saying on here that I've never had luck keeping Siamese fighter fish. I have years experience in the hobby but every time i get a betta they die within hours of getting them. Its been a couple of years since i tried keeping them so thought i would give it a try again. This time buying the fish from a proper retailer, not one that sells half dead stressed fish. So i picked up 3 betta fish off eBay, they arrived today. 2 of them gone into separate 5g tanks and one of them is in a 1.5-2g? tank. The one in the 1g tank is acting rather strange. It swims round but then rests for a while on the bottom. Is this normal betta fish behavior why they are settling in? Just got me a bit concerned as the other two haven't stopped swimming since they gone in the tank. All tanks are filtered and heated.
