Plant leaves going brown

Hey guys

Please see the pic and the brown leaves in the red circle. Plant's been in indirect sunlight for just over a week, and 2 x 39W T5 6500k for the last three days.
Colour change started at the tips of the leaves and is working its way down the plant.
Dosing with PRODAC Liquid Fertiliser.

What's up with my plant? And if someone knows, please let me know what I'm doing wrong. Would hate to lose it.

 

I don't believe that is a true aquatic. @azurekoi can differentiate with his plant powers.

 

The plant further forward doesn't seem to be regressing at the same rate, but one can also see the brown starting at the top of the plant.
Thanks for drawing this to the attention of azurekoi.

 

lol - bought them as a Aquatic Fern at a certain large LPS in the East of Pretoria right? sad news...it aint a true aquatic....

Not sure of the species name of it... and never kept it myself...but I think for one thing that it does not like having it's rhizome planted in gravel....try tying it to some driftwood.
@Barry.M had some of this in his tank a while back...Still growing Barry?

 

Yep, still growing. Also got it from the same shop! Definitely tie it to a stone or piece of driftwood. As soon as the rhizome is buried in the substrate, it will begin to rot and die! here it is, just before I trimmed and moved it. (Had to trim as it got covered with algae) I moved it to a less lighted spot and it seems to be recovering... I trimmed it to about 2cm from over 15cm.

Sorry for the poor quality photo.
I have another one attached to a piece of driftwood, next to the filter intake.

 

AWESOME! Nice ot know it does make it under aquatic conditions.... Thanx Barry!

 

I no know that it isn't a true aquatic, and has still retained the immersed leaves. How it remains alive is a misery! Haha... I dose the tank with Microbe-lift Bloom & Grow, maybe it likes the 30 degree temp as well?
(It's astonishing, what can be achieved by people who don't know..... "That you can't do that!")

 

Thanks for the info, Barry!
I have my ferns on driftwood now. Lightly pushed into recesses with some wool.
Would you recommend scraping the roots to get the black muck off? Roots feel like wires, though.

 

I've just read my previous post and meant to say "mystery," not misery...

No, don't scrape the rhizomes at all... Just let them settle a bit. If you see, after a few days that they seem to be ok, you may (very lightly and gently,) scrub the rhizomes under fairly fast running tap water with a soft cheap new tooth brush, so as not to damage the fine feeder roots on the rhizomes. Don't use an old one, you don't want old toothpaste residue to get onto the rhizomes and into your tank.

Holding them in place with wool, might work, but think that they prefer to have direct contact with the water. I either tie them onto the driftwood with a closely matched coloured nylon cotton, or superglue them onto it. If using superglue, use the best quality you can get and make sure the driftwood is very dry, It is harmless to fish and by the time it dissolves in the water, the rhizomes should have attached themselves to the surface. (If you get superglue on your fingers, acetone removes it completely.) Superglue will turn white when it is exposed to water, so try be careful how you apply it.

By the way, be prepared in case the ferns do not survive in your tank, remember that we aren't sure that they're fully aquatic. I think that I was extremely lucky with mine... They could be bog ferns, or ferns that grow at the river's edge. If they don't survive, don't look on it as a failure, people who never make mistakes, usually never make anything...

 

LOL -I thought this was a clever play on words...
