What would be a perfect filter for a 30 gallon tank filled primarily with anabantids they will be sharing with a few compatible species in a planted tank? There will not be many other fish other than the bettas, and they have to accept optimum betta conditions (80 degrees, planted, neutral ph
and slightly acidic. She plans on having blackwater tanks later for her "retirees". The tanks are made with removable flow-through dividers to keep bettas separated, though small tetras, shrimp and snails can still manage to change locations. And are two small bio-wheels on each end better than one large powerful one?
My daughter wants filtration and areation even with plants. She adamant on keeping stable controlled conditions, she even bought battery operated filters in a bin lot. She plans to keep the water level as low as 3 inches below the top lip. She wants to know the best brand and if she needs to adjust the tank order to have a cutout dip where the filters are to be. she doesn't want too much flow annoying her heavily finned show fish (they arrived to today before she got home. Lovely little things).
So throw some brands out and whats good so she read over my shoulder to decide. And I can help her pre-order her things and figure the dimensions.
