Dwarf Pennywort?

Here is a pic of a new plant. It's not as good a shot as I would have liked... I need to work on aquarium lighting for photography but that is a whole other topic.

The LFS guys didn't really know what it as but had grown it in the past. It can get to about 12" or can be cut back to leaf out. There are about 4 stems in there.

I believe "dwarf pennywort" is usually deemed to be Hydrocotyle sibthorpioides and this grows along the substrate like a sort of carpet plant. I've never had it, so I can only go by online photos, which of course are not always accurately labeled.

The leaves in your photo do have a pennywort-like shape.

Something we all need to remember: The fish you've acquired was quite happy not being owned by you, minding its own business. If youíre going to take it under your wing then youíre responsible for it. Every aspect of its life is under your control, from water quality and temperature to swimming space. [Nathan Hill in PFK]

it looks like cardamine lyrata :) I find that it grows best when you tie a batch around a piece of rock or drift wood which will give this messy stem some form :)

I was looking at how it is growing and noticing that it seems to have a lot of "roots" showing up near the top and it's not really going straight up either... very easily displaced by the slight current near the bottom of the tank.... and I got to thinking that it might be better along the bottom as opposed to going up... so I may give that a try. I was considering putting a driftwood plant up near the surface and moving more of my java fern lower too, but this looks like it needs more light than it might get there so I may try a stem up there and see what happens.

I just looked it up, bright, cooler temps... well, it's similar looking so we'll see.

It's not a hard plant at all. can get a little weedy. I plop it in my 1 gallon which I place on a lowlight window sill and it grows just fine

Is that dirt in the bottom?

How often, if you do, do you change water?

I'm probably going to have a plant only tank at some point and would love to do it with as little hardware as possible... that looks to be a nice minimalist setup. Details?

hmm... I have cheap potting mix on the bottom capped with black sand...

best way to grow this is actually to do a dry start with miracle gro organic potting soil. capped lightly with floramax. Then separate the cardamin lyrata nodes, plant spacd evenly and wait until it carpets the bottom. the stick in a ziploc bag and pour water ontop(so you dot have stuff flying everywhere). This method works very well if you dry start your tank for a month or two before flooding.

I've never changed the water in that tank. I'm not a keen water changer tbh >.>
the same with most of my jars.
