Rust Pinholes on Leaves

[simon_the_plant_nerd]

Brown pinholes in leaf. Only on the old leaves of this lagenandra. Doesn’t affect any other plants in the tank. New growth unaffected (yet).

Curious what potentially could cause it? I’ve changed the tank around a bit recently so it could be adjustment to new parameters.

90L tank, 25C.
CO2 injected to a mid green (not lime green).
Light is broken currently but maybe medium levels of light.
Ferts are Solufeed. Use the trace mix and macro mix. Have been using the same for about a year. Both dosed 12hrs apart using dosing pump.

Neon tetras, one golden ram, bristlenose plec and a couple of corydoras.

I have done some investigation and I think I know what the problem is but I’ll wait for some answers just so I can confirm my thinking without introducing bias.

Hi all,

It looks like mechanical damage to the leaf edge.

Yes, I think the edges have been eaten by a plec. I removed this one as it’s damaged but there’s a few other leaves still on the tank showing brown holes.



Any thoughts on the small brown holes?

Hi all,

Not really, but it does look quite an old leaf, so it might be natural senescence?

I’m showing signs of senescence.
