hi. i got my 2gallon tank at petco. its the kit. of what i read the pump acts as the filer as well. I wosnt going to use the air pump but i read that battas like "moving water" and my boy seems to love it. the air pump is not all that strong so its perfect. I still change his water 100% 4-5days. im still pretty new to bettas his my 1st one and had him for about a month.. he seems to love the tank. i had a 1gallon for him but it didnt seem big enough for him to really have a happy life. the only mistake i made was get fake plants..poor little guy got a hole in his fin probably from playing in the plants..so i went out and got a real plant he seems to love it. (the hole healed in 2 days) goodluck! cant wait to see pics of your betta!
Hi there, I'm new to this site and saw a picture you posted of your tank on one of the threads. I don't have a betta yet but I hope to get one soon. I noticed your air pump and stone, it looks like the same as mine. Why do you put it in a clear tube? Is that to reduce the water agitation? Also, do you have a filter? My tank is about the same size as yours too and the pet shop said a filter isn't necessary if I have a pump. Thanks for your help :)
