HI everyone! I just found the forum and I think it's great.I am a new fish owner.I actually just bought a Betta fish yesterday.He is a veil tail Betta, about 6 cm. I am keeping him in a small tank, a 2.2 gallon.I am fully aware that it is a pretty small tank and I am going to upgrade in about 4 months, 5 tops.I was told he will be fine without filter and heater but I am planning on buying an equipped 5.5 gallon tank when I upgrade.Right now Chuck has natural gravel and a cave/log.I intend to buy him a natural plant but I was thinking I should wait until I upgrade,when I want to also add a snail and 2 small size cleaner fish(or even one as long as it doesn't need a school).So what could I put in the tank to keep him entertained in the meantime? Also, should I do 100% water changes or partials and in whatever case how often should I do it.Please, I know it's a small tank and he will not permanently live in it,I am trying my best to give him a good life with what I have right now.I just really hated seing him in that tiny cup at the mall...So please tell me what else I could do for him in the meantime? Like what toys could I add and stuff.Thanks!
