I currently have a female betta in a tank that is too small for her but is maintained through regular water changes and the use of Prime. I have had her for nearly two years now and last summer I bought her a 10 gallon tank only to find out she has swim bladder. She was okay for a couple of days but then she appeared bloated and was swimming on her side. She would try to "dive bomb" to the bottom of the tank but with no avail. Eventually she just wedged herself between decorations and stayed like that until I put her back into her old tank. Of course she was mad at me. But I hated seeing her like that. I think the depth of the tank is what caused the SB to flare up as she has no issues since then. I've looked at PetSmart and Walmart and they have smaller tanks than what she's in or ones that feel flimsy such as the Aqueon Mini Bow. I came across this on eBay which looks decent but have no knowledge of the tanks reliability - http://www.ebay.ca/itm/Tetra-29095-...LH_DefaultDomain_0&hash=item5666b26858&_uhb=1 My question is for those of you who have smaller betta tanks, what do you use? I am in Canada and have a PetSmart and Big Al's locally, along with independent LFS. I'm not opposed to purchasing something online as long at the price is decent. I'm looking to keep the tank under $50. It doesn't have to come with a built in filter, I can purchase that myself. Any suggestions are appreciated! Thanks.
