What Plant Is This ?

[moochy13]

my swords used to be mega, as you can see in my sig, but then something happened to them. im not sure what. i split them to give some to my mate, and they never grew back. i thought splitting them had ruined them, but at roughly the same time i also upgraded my filter. is it possible the new filter was removing too much natural plant food ? i also had a crypt that pretty much completely melted.

today i put some new swords in, and took the old ones out. however i have also yesterday put an even bigger filter on, and if this was why my plants stopped growing, i dont want it to happen again. so i guess i would need some plant food or something. theres a lot of (too many) fish in my tank, so i guess theres plenty of plant food being created.

secondly, while buying the swords i got drawn to this little plant, thought it was really nice so i brought it. he said it was some sort of sword aswell, i wasnt really listening to be honest

Hmmm, I'm thinking Echinodorus sp. possibly cordifolius

Lovely looking healthy plant there...

Your filter won't be removing the nutrients you are adding. Swords can be hard to grow for some people. They are usually grown emerged i believe, so as you submerge them in your tank they need to adjust to being grown under water. Similar to the Crypts that you mention.
