Default Amazon Swords holes in leaf... iron problem?

Hmm... yes lighting could very well be a problem considering i only have the
default strip of light. So bascially getting by with just the 1
watt/gallon.


Are you sure you have 1 wpg? I believe the standard 90 gallon tank hood has
one 40 watt bulb. That's less than half a watt per gallon. Even if you have a
twin-tube strip, with two 40 watt bulbs, that's less than 1 wpg.

Also, 90 gallon tanks are deep -- over 25". The only difference between a 75
gallon tank and a 90 is that extra 4" of height. It can be difficult to light
tanks that deep.

I thought perhaps the light would only make it grow slower (I
didn't think swords needed very high light intake)... i'm just happy if it
grows and stays alive =)


I consider swords to be moderate-light plants. They definitely need more light
than java fern or anubias.

Would the normal iron tables at LFS do the trick?


No. You can't make up for low light with fertilizer. I don't think your
problem is iron deficiency, anyway.

Here's a pic anyways of the plant

Hmm. That does look like it might be pl*co damage. (Though it might be that
he's just feeding on dying leaves, and the algae they attract.)

You might try bribing the pl*co with fresh veggies at night. Cucumber,
zucchini, peas, green beans, romaine lettuce, spinach, etc. See if that helps.
