The tank looks nice, however I see something I feel I should warn you about.
The plant with the light edges is not a true aquarium plant. It will live for a while but then will die off and mess up your tank. I had this happen twice before I learned better.
That particular plant is supposed to be grown emmersed (top sticking ot of the water). Unfortunately a lot of lfs
's sell these as well as others as aquarium plants, but they're really not. The best thing for it would be for you to take it out, put it in a pot on the windowsill, and put something different in the tank. May I recommend something with lowlight requirements like an anubia or a nice java fern?
The betta is beautiful. It appears to be a veiltail, defiantely male.
Anyway, welcome to AA! There are a lot of people here willing to help and I hope I have done so.
