As i said in the topic, I was wondering what kind of plant this is, its grown rampantly in one of me tanks and grows very tall and even out of the water if left untrimmed.

looks like Hemianthus but I'm no expert here.

Hi Dean, a bit hard to tell from pics but I reckon it looks like one of the Bacopa species (poss. caroliniana). Does it have thick leaves?

It looks like my Bacopa Australis

Id reccommend trimming it though as I shouldnt think a lot of flow gets through all that?
