Hi joycould,This is a 2 gallon betta bowl that has a java fern, java moss, anubias, a bit of hornwort, a little crypt and what I think is rotala rotundifolia. The rotala is really the only thing I ever trim. There is some red rooted floater on top that is just starting. The light I use is a desk lamp with a compact fluorescent bulb, no filter and no heater.
How often do you change the water wtih this setup?
Also, about how many percent water change do you do each time?
