Lacy brown holes in leaves?

[Aeonflame]

A potassium deficiency starts with tiny holes fringed by yellow tissue. the holes eventually widen as the surrounding leaf tissue rots away

Yes, I do have many fish for the size of the tank. Ten fish. Most of them are very small though (if that makes a difference?) , and I've got two sponge filters. I do a water change every week and I've not had any problems so far - unless this thing with the plants could be as a result of that? Yes, the ammonia reading is 0, taken at the end of a week just before a water change.

I dont have any problems with algae, my fish are not dying, and the tank has been stable for 4 years.

I know it is not ideal and hope to get a larger tank soon.

Hmmm... do I smell a troll?

Most of these 10 fish are small after 4 years??

Fish grow after 4 years and 10 fish would kill each other in 8 gal, let alone die off from ammonia poisoning.

Oh Brother.

"I have an Angel, some Silver Tips, some Black Nuns, some Bronze Catfish, a small brown loach, and a tiny algea eater - a plec?".......

REALLY? In 8 gallons of water and you are worried about this plant? No way are those fish 4 years old.

That plant looks like a purple passion. A houseplant.
