I have posted prior to ask about my Betta in a planted smal 2 gl tank, some replied noting that the tank a) is too small, b) bot a true walstad planted, my issue is that this Betta was given to me, I have 2 other tanks. One 6gl with a male beta, the other is a Long 10 gl tank with a female Betta .. that betta in the small round 2 gl bowl if I add 80% of live plants as it was suggested can I keep him.in there, or should I move him in the 10gl tank which has the female * other fish. see pictures

walstad does it require, air sponge filter. Ionly have a beta fish it's a 2 gal bowl and live plants
