Plant Id And Why Are Some Dying?

I'm currently cycling a new tank - day 2 of the fishless cycling method. It has the following
Sand substrate
2 x 45 tubes on for 5 hours off 2 hours and then on 5 hours (siesta method)
Dosed Seachem Florish at recommended levels
Dosed Seachem Floursih Excel at recommended levels
180 litres
Tetratec EX700 filter

I'll post the stats tomorrow as I'm off to bed soon.

None of them were labelled in the shop so I don't know what I have. Identification appreciated by anyone that can tell from my rubbish photos.
Some plants look like they are not doing so good and I'm a bit disappointed at the number of floating leaves and brown areas that are developing.


This one looks ok but some leaves look a little brown


This one looks ok too

More pics to follow


This definitely looks ill


This is possibly the worst of the lot. Most of the lower leaves have shrivelled up and gone brown.


Not sure about this one, could be ok...

Thanks for any assistance

1st pic looks like baby tears
2nd pic, no idea
3rd pic & last pic look like Ludwigia natans
4th pic, plant with round leaves if Hydrocotle and is a type of lilly. It likes to have the leaves floating on the surface and rots when kept underwater.
5th pic looks like a green form of Rotala macranda

Cool, thanks Colin. So that is why no. 4 is doing so badly. Funny as the lfs had it rooted to the bottom too. So is it just supposed to float around then and not be planted in the substrate?

Hydrocotle is a marsh plant that normally lives in shallow water and the stems grow up to about 6inches and the leaves float on the surface. Unfortunately it grows on long rhizomes and most people think because it is long, it can be planted in the gravel and grow like a normal plant. It doesn't work tho.
When grown across the surface it provides a good habitat for baby livebearers and other surface dwelling fishes.

I've also just read that it needs a lot of light, so it sounds fairly unsuitable for my set-up. Typical, I've yet to find a lfs that labels plants and has staff that knwo anything about them. Maybe online ordering is better in future as at least you can research a named plant before buying. Thanks for the information. Now if I can just find out what number 2 is....

some plants require different conditions of water, like a certain ph or something. When buying plants its good idea to ask the people that work there what sort of waters the plants prefer

or

most plants die anyway, happened to me alot . sometimes its just natrual or mayb snails


also from looking at your plants, all your dead leaves are at the bottem which means they may not be getting enough light.



hope this helps



p.s. im learning too :

Keeping that plant planted shouldn't be a problem. I have it planted in three tanks. It has been that way for a long time. It is growing very well. I also have some floating. Mine grows better planted...
You can snip a little and try it both ways. Then you can see which way works better for you.
There are lots of us growing it planted and floating... It does not have to be pulled up unless it just won't grow for you that way... It can be done both ways.

The macrandra need high light,co2 and good nutrients

The 2nd picture of Potamogeton gayii it look like its going good. The color can range from green to bronze.

hey frozenbarb

is the Ludwigia repens, natans or palustris? I've seen it called different things at different places and the books all call it different names too. I've always known it as natans.

You could be right about the light. The tank still has the standard tubes that it came with so they are probably insufficient. Can anyone suggest good plant growing tubes for a Juwel Rio 180?

Well I've now moved it so it is out of the shade of the Potamogeton gayii (2nd pic) but at least half the leaves have come off or shrivelled up. Think it could be on its way to plant heaven...

Sounds like the macandra might follow it unless I act fast. Thanks for the info frozenbarb!

Sigh! The macandra pretty much disintegrated and I had to pull I out. Made an awful mess of the tank. I really must do more research before buying plants next time. I also just found out that I don't have two 48 watt tubes as it says on the Juwel website. They are actually 30 watts so I have even less light than I thought!
