I use low light only 60 watts on this tank. Low light plants. And I used Flourite for the substrate. I use excel three times a week. Same think I did when I had them in the 29. I used only 30 watts of light and the same set up for it and it did great for 9 months. Gave me the courage to move it all to the 55.
Right now there are 6 guppies, 4 female betta's, one angelfish and the two BN's.
This tank use to be my goldfish tank and I just set it up a couple weeks ago moving everything from my 29 to this tank. I have new growth and everything is looking great so far.
Going to add a few more female betta's at a later time. And hope my trumpet snails do just as good in this tank as they did in my 29. I just love those little guys.
