This is a photo of M. quadrifolia in its emersed growth state. When kept in an aquarium for any length of time it will revert to its submersed growth state in which the four-lobed leaf structure changes to a larger single-lobed leaf structure reminiscent of Glossostigma elatinoides, but noticeably larger in size and darker green in color.

not a good carpety plant for tanks with fish that are active on the substrate. Corys, clown loaches, etc. They spread by runners on the surface that these sorts easily dislodge. Very much a pain to reroot these runners...almost impossible...unless...i've had some success (since i have two clown loaches and one bicher that dislodge these guys alot) by cutting off sections of the runners from the source and rerooting them...easier to keep down in sections rather than the whole thing (the runners will go out as far as your tank will let them). Also, it's any ugly transition between the submersed growth style they are shipped in, to the emmersed style you will keep them in. The taller clovers that came with the plant will be looking really out of place once it starts spreading and growing like it does underwater...some will die off, but eventually to make it look good, you will want to cut down the tall's alot of work as once you cut a shoot, the remaining part doesn't die away...and it's a finicky business getting scissors down far enough to cut everything.

Looks nice in its submersed form. It stays planted in a tank with fish that have pulled up most carpets I've tried (I have a mischievous ram). My only problem with it is the rate of growth. I have it in a 29 gallon with medium lighting, co2, and ei dosing and after being planted for months it's not anywhere near being carpet.
