Helanthium: Tenellum Green vs Quadricostatus

[valevelo]

I've got the two in a couple tanks and noticed the Quadricostatus is growing a lot better than the Tenellum Green, which seems to be slower spreading and also suffer more melt. These are reasonably new setups (fish been in for 2 months), no CO² and minimal feet at the moment. Both were origjnally Tropica in-vitro pots, with runners moved from the first tank to the second.

Is this just a quirk of the plants? Seems to be the first plant in the runner (ie the one planted with tweezers), so maybe it's my technique and the Tenellum is more delicate.

Quadricostatus grows much, much faster in my experience

Tried it in my shallow and got rid of it all a wee while after….jesus it doesn’t hang about in taking over.

Thanks all, as long as it's normal the Tenellum is slower I'm not worried. Easy enough to thin out some Quadricostatus runners as and when. Got some Cory fry in the tank at the minute which appreciate the cover so will leave it alone for a bit
