Rotala sp. Bangladesh
 
Anyone have any info on this plant? I'm currently scouring google for images and for info on growth rate and all that kinda stuff. I'm also trying to figure out where in my tank to put this plant lol

most rotala grow very quickly and are very weedy. They will pretty much grow as high as you allow them to but they can be trained with pruning to stay lower.

Last thing i heard was that it was thought to possibly be a variation of Rotala mexicana. Not sure whether that has been confirmed yet or not.

Anyone else own this? I'd love to see pics of other peoples.

Not sure if this would be better as a mid-ground or a background in my tank.

Once established, it is a weed. In a high-light environment, I have some 36"+ stems trailing the surface. It is not a prolific brancher. IME, if you top it, the top portion tends to rot with a few side shots forming lower down the stem. I also find it prone to melting when re-planting or moving between the tanks. The bottom of part of the plant melt but with the tips continuing to grow.

The picture below is somewhat unusual for me as it only gets that color right under very intensive light. Otherwise, it mostly stay green with dark burgundy stem. I'll try to take some pictures of the 'normal' form.

Cool, thanks :D

I'm just trying to figure out what to do with it, cause my tank already has L. inclinata 'Cuba' and 'Pantanal', which both look very similar to this thing, or at least the Pantanal looks similar.

Bangladesh is a much smaller, thinner plant then Cuba or Pantanal....

HybridHerp 01-16-2013 01:15 AM

Really? I got it from Barthog and tbh it seems just as big as the cuba I got

Its the one that is taller with a red stem. That's what I got as R. Bangladesh. The thing in front that is slightly pink is 'Pantanal' and Cuba is somewhere in that mess as well.

I just planted it all last night, and these pics were right after planting, so the plants hadn't adjusted or anything yet.

A near certainty

That doesn't look as r. Bangladesh to me either.

R. Bangladesh has smaller stem & thin leaves.

It came from a friend who visited Tropica in Denmark. It was in one of their display tanks as a test plant they decided not to use in their line-up for one reason or another. It's almost certainly a variety of mexicana.

You won't find much info on it because outside of the few people who bought it on here or APC from the few of us who have it not many people have heard of it.

It's pretty easy to grow. I've not had the same issue with topping it. I always top my Rotalas and leave the bottoms to regrow.

That's because the 'cuba' is significantly undersized.

This plant is difficult to scape with since it grows so damned fast once it gets established. You probably need to trim it once a week to keep it in check and not strewn across the top of the tank. Maybe if you dose your ferts on the lean side it it won't be such a weed. OVT's pic is the nice growth you can get from Bangladesh but it also grows very lanky as well. I had it growing under a 4 bulb Tek and sometimes it would grow nice and compact and other times it would grow lanky with long internodes.

I thought so as well, but idk what else it could be, plus thats what it was given to me as. What do you think it is then?

For now, I'm just going to assume its R. Bangladesh and treat it as such.

Agreed. The taller one with the red stem in the picture looks like Ludwigia 'Cuba' to me. It's a bit stunted, but that's what it is.

+1

They look very similar which leads me to believe it to be a varient. But I'm not a botanist.

What was pictured above, however, is not 'Bangladesh'. Sry.

And saying it grows like a weed is just a bit of an understatment. :) Given the right conditions, this guy will just go absolutely nuts!
