Ok I tried ottos but they didn't make it not enough brown algae in the tank at the time and I didn't realize I also had to supplement their diet. After some reading and educating myself more about algae eaters I bought two gold brown algae eaters tonight. I have alot of brown algae in the tank now and read that feeding them zucchini to supplement their diet helps is it ok to use frozen zucchini that I defrost or is fresh better I also heard that boiling it beforehand is better? Also how often do I feed the supplement to them? I was wondering would spirulina flakes also be a good supplement for them? Any advice would be helpful as I want to take very good care of these guys.:grinyes:
