So, I have a 1 gallon tank at my desk at work with a male Blue Halfmoon Betta. Originally I got White Ribbon plants and the filtration was an under gravel air stone thing, didn't like it and I found that the White Ribbon is not a submersible plant and would have drowned. Took those out, tried the betta bulbs, those didn't really work as I had hoped. I took them out and placed them in a separate container with some root tab fertilizer to see if I can get them to grow any. Recently put Amazon Sword in. Changed the filter to an air powered "powerhead" with a carbon filter. The pump I have is able to vary the amount of air flow. I have it set low enough to move the water through the filter without causing surface flow or too much movement in the water column.
I have been keeping cold water fancy goldfish for years, but have only just started with tropical fish. I currently just have one betta, after not having any succes with mollies and platys! He is in a 30l biob, with heater, filter and decorations. I have been feeding him blood worms and specalised betta food.
Very pretty set-up, Karen. I also have a few goldfish.... 3 fantails & a lionhead. They're all juveniles, the largest about 2 1/2 inches.
