    Are either of these hard to keep? They are in a long low tank with LED's overtop, daily Excel dosing. Do i need CO2 to make them happy? I planted them all yesterday and they were all standing straight up this morning.

    just wanna keep them alive and happy and have them fill in as a possible carpet lol.

    I've had parva, and it never did much for me in a low tech tank. It hung on for a long time, but didn't spread well. I've read that in order to get a carpet from C. parva, you have to dry start them, and even then it can take a while. I haven't kept C. petchii.

    so if i have the invitro parva, it comes in lil clumps, would it be best to break up those clumps further? Last night after work, i noticed the petchii seemed to be doing really good, the parva was still just green and there lol

    so an update, the petchii is filling in fast, like much faster than i was expecting.. the parva is filing in, just not anywhere near the speed of the other one. petchii might take over the tank at this rate.. lol.

    I would split it personally. Mine seems to like growing in tight clumps to a certain point and then slow down

    petchii is still spreading fast.. must be great for them.. the parva are growing and spreading, just much slower. Wonder if its at all possible that the petchii leaves are slightly wider, thus getting more light to help them grow than the small parva? IDK, i just like how plants look :p
