Hello everybody, I was just wondering what would be considered a "beginner" red plant. I have a 29 gallon tank with 48 watts t-5 ho lighting via an Aquatic life fixture. The light is mounted to the rim of the tank using the supplied legs. I used pressurized co2 and started dosing EI dry ferts.

some plants that interest me are:
Alternanthera reineckii 'rosaefolia'
Ammania gracilis
ludiwigia "red"
maybe some rotalas?

Don't start with the Ammannia, it is a tough plant to grow! Persicaria [Polygonum] sp. might work though. Both are quite a large growing plant for a 29 gallon tank however. Ammannia well grown has a stem-leaf width of about 8". Mine is feeling poorly and is about 6" across and my fairly happy Persicaria Kawagoeanum is about 5" across.

I haven't grown Alternanthera but Rotalas and Ludwigia should work fine for you. Ludwigia 'Red' has grown out very well for me.

Hi. MMF, I agree with Kathy. My first red plant was a red ludwigia and its responding very well to liquid ferts 110watt T5ho and co2 in a 55 gallon! I see no problem with your setup for that plant not to thrive. Many people have reported keeping Nymphaea rubra in moderate/low tech setups with success and their really red too!! Also if your feeling confident enough give rotala rotundifolia a shot! It will show deeper reds in higher light but still looks great in lower light setups! Good luck with your search, hope We can help!:)

depends on the reflectors. i had 72 with coralifes o nthe tank of my 29. barely turned pinkish touching the suface of the water
i have 96watts wit ha tek hung about 11 inches over the tank and it'll get red if it touches the surface of the water

when i used 48 wats with the tek 3 inches above the surface. it turned red 4 inches from the surface of the water

it depends on how much light actually makes it to the plant :)

My very first red plant was the A reineckii so I would definitely suggest it.
I also currently have sunset hygro, not necessary red, but displays a nice pink color.
And my last recommendation is Limnophila aromatica. These can turn a nice purple-reddish color.
I have all 3 in my tank, no CO2 and they look pretty good. You wouldn't have any problem with them with your setup imo.

Alternanthera reineckii 'rosaefolia'
Limnophila aromatica
Dwarf Red Lilly
Tiger Lotus

These are all easy and will even grow well in a low tech mid light set up easy.

And I agree with Blazing wolf on the Repens.. Needs lots of light.

REPENS, is not a good red plant for beinngers. it needs LIGHT
plain ol ludwigia however is a differnet story it grows red just about anywhere
I'm a little confused by this --what do you mean by "repens" and what do you mean by "plain ol ludwigia" ? When I hear "plain ol ludwigia" I think of Ludwigia repens.

Thanks for all the replies! It seems like alternanthera is the way to go!
I have had ludwigia repens previously, It grew very well but only had pink undersides. The only reason I got rid of it was a temporary loss of sanity one day during cleaning!

I might also look into ludwigia "red" and the l. aromatica.

I will keep everybody posted as I am hoping to do some rescaping soon!

Ludwigia sp. 'red' is possibly the easiest plant to get to deep true red (not brown). Very easy to grow too!
