ok, Im going on hol Sept 14-25, when i get back Im getting my first Betta, thanks to all your advice here, I think I have the perfect home for him/her, I have been told that they like aged water, question is, when I get back should i fill it with water from my other (very healthy tank) and add the biological starter etc or just run with a bag of gravel and water or just tap water with dechlorinator and bio-start, my instinct is to use half tap and half other tank water, plus a bag of gravel , plus the bio start for a week or so,then take out bag of gravel, obviously I test water regularly but is this too much?also if running empty(with any of above) should I still add a fish flake to feed the bacteria,also I have two hockey sticks that could go in (either temporary or permanently) what do you think, is having a couple of other fish beneficial for a Betta or are they ok alone?
