Just thought I'd update you on where I'm at with my Sword and tank. My Sword had split off a baby plant from the side of the middle and obviously the new leaves were progressively more from the new baby. The old leaves have hung in there but maybe it's time to split the baby off.

My plant looks like yours, with a tip of a leaf left with nothing but connective tissue remaining, like I see in your picture. This, I think, is a sign of a nutrient deficiency. I also have a plant or two showing pinholes, which tells me that I definitely have a Potassium deficiency.

Maybe I nieed to dose more Flourish Comprehensive, I certainly need to dose Potassium. Of the other NPKs, I rule them out (Nitrogen, Phosphorous) because they're available in the environment. I am also using Seachem Root Tabs (one under the Sword last week). So if I dose more Flourish Comp. and add Potassium, I should be alright - we'll see if the other two macros show any deficiencies - I only have seven little fish in my 10g. The tank was started on 4-18-12.

Byron,

The pic of an E. major came up in the listing in the opening page here, and I looked at it. I think the leaves are narrower and it looks taller than my plant. So, I think you may be perfectly right in your initial estimation of the species of my sword - E. osiris. Hard to tell. Just wanted to let you know about that.

Not necessarily. I had this same condition in one tank, and I increased potassium [I have been advised by those who supposewdly know that potassium in excess should not be harmful, thus I gave it a try] but it did not help and seemed to make things worse, though that may just have been co-incidence since I do not yet know the exact cause behind this. I do know that increasing Flourish Comprehensive to 3 times a week from 2 did help a bit; this tells me some nutrient is insufficient, but pinning it down is not easy.

As noted above, not necessarily. I would add another dose of Flourish Comp first [how many times a week now?] and continue this for 3-4 weeks and observe any changes.

One planted tank person suggested to me that nitrogen was the issue, and I should be dosing nitrates. This I am not likely to do, for the sake of my fish. I would increase the fish load to get more nitrogen [ammonium] but not start dosing nitrates beyond what little is in the comprehensive and tabs.

Thanks for the added info and help. I think I'll start by dosing flourish twice a week for now since it's the easiest fix at the moment. If that doesn't help I'll look into what might be the exact deficiency.

My tank currently has 10 Emperor tetras, 4 black widow tetras, 2 keyhole cichlids, and countless MTS. I had angels and cories but believe they were just out competed by the tetras for food. They're very greedy fish and swim to the top or the substrate and scoop up any food before the other fish manage too. No matter how I fed them sinking or spot feeding the cories and angels just weren't fast enough which I think led to their eventual death. You said adding fish for nitrates might help but am I close to full capacity and if not what fish do you think might stand a chance?

I was speaking in general terms; if nitrogen is insufficient, adding fish to increase it (via ammonium) is the only practical solution. But other factors play into this.

Angelfish are not good tankmates for the two tetra mentioned, so that is not surprising. As for corys, feeding sinking foods after total darkness works as they are nocturnal.

Byron,

I hear what your saying, but I was able to definitely diagnose a Potassium deficiency in other plants right now, and that means that the whole tank is insufficient in Potassium, if you will. I'll start at half-dose and see what happens. I am still glad to get your advice.
