Hi Adrienne
Thanks for your reply. My tank size is 30 litres but only had this half filled with water which had
been set up 2 wks prior to adding my Betta. The tank had been cleaned out before setting up, using warm water. The filter I was using in this tank was an external one using a spray bar the filter is a Crystal 80, however I changed this to a foam filter as I found this to be a bit overkill.
My second Betta went into my other tank a Jewel 125 using their filter system which was a running community tank which contained my 2 female Bettas, and some Tetras, I had the male in a breading trap attached to this tank. Yes I did purchase my Bettas from the same place, I find that they are very knowledgeable and keep there tanks and fish in excellent order. My first Betta was kept in the small tank by himself.
