I'm thinking about starting a planted tank. It would be a 29g with sand substrate and house a hoplo cat, a SA bumblebee cat, madtom cat, and probably a rubberlip pleco. I like sword plants and would like to have a few of those unless theres something that would work better for these fish or be easier to take care of. I'd like to avoid a CO2 system if at all possible. I don't currently know the wattage for my lighting but that can always be changed to fit my needs. Any advice or suggestions would be appreciated.
