Parameters for Kuhlii and Rasboras planted tank
I have the substrate, http://i97.photobucket.com/albums/l2...sSmallest5.jpg
I need to know what the best KH, GH and pH would be for typical rasboras and Kuhliis. Tank will have Anubias for sure and likely some other plant, some sort of soft water plant if someone will recommend one that I can get locally. I think Bacopa caroliniana is supposed to be a soft water plant so I might try it in there as I already have it.
Chris, to answer your question, both species thrive in soft water but I see no reason why you should bother with your water parameters unless these are wild-caught species. Captive-bred specimens are fine with various range of water conditions.
Bacopa Carolinia thrives in my loach tank, and the water is pretty soft in there. (The light is pretty high, though - 3.8 WPG) I have had less (but not zero) luck with Bacopa under 2.2 WPG in a 55 with even softer water (unfortunately, the plecos kept rooting it up at night.)
I have dwarf sags in both my main loach tank (where they've grown into a lawn), and in my kuhli/oto/threadfin tank, where they're taller and don't spread as fast, but are definitely growing (15 gallons, no driftwood, 18 watts of light, but near a southern window.)
Another one I've had good luck with in soft and medium soft water under high and medium and low light - rotala indica. Makes a great, bushy, background plant if you trim it early and low.
You might could have better luck with the kuhlis if you put a sand patch in there. They love to dig.
I thought about getting sand. I tried to get the smallest gravel that my LFS had in order to help the Kuhliis be able to dig and play in it. We will see if it works or not. If not I will switch to sand. The gravel is actually pretty small on average. BB to airsift pellet on average. I have even thought about getting 20-30 pounds of it and sifting it so I only get the smallest grains. Have to add some more anyway so might be what I do today.
I will try the Bacopa, I am also gonna try to get Bacopa Australis if I can find it. Looks like a faster grower and might be just what I want for the tank and my purposes. I only have ~35 watts over the tank so high light plants grow terribly slow for me.
