Nutrition deficiency or fish bites?

[nijat11]

Hi all!
Could you please tell me is this nutrition deficiency or my bristelnose plecos did this?
filtration is 6500 l/h pump + maxspect xf350 during photoperiod.
Fets EI dosing. Water change 50-60% per week.
CO2 injection.

or my bristelnose plecos did this?

The majority of that damage is down to the Bristlenose plecos grazing on those sweet echinodorus leaves. It's possible the leaf was weakend and became more susceptible to Mr & Mrs pleco, but knowing what I do about the tank (aqua soil, ei, eddha fe, root tabs etc) a nutrient deficiency is unlikely.

Feed the plecos some courgette, that might help.

If this appears within weeks after introducing given Echinodorus into the tank, then the plant is replacing leaves created during emerged life by new leaves made for underwater conditions. Both these leaves often seem identical but in fact morphological and functional differences are substantial. That's why it pays off for the plant to re-mobilize nutrients and amino-acids from old leaves to use them for creating new leaves. The old leaves then appear sick, damaged.

It is not new. 9 months

It is not new.

Then, by the appearance, I'd say the plant is not feeling well and subsequently some fishes attacked the already damaged leaves. It may be nutrient deficiency, but it may be something else, as well.

@nijat11 is this the same tank that you massively overdosed easy carbo? Echinodorus and large doses of glutaraldehyde generally don't end well.

Okay I will stop dosing for a while.

What kind of deficiency ?

To be honest I don't think its the daily recommend dose of glut that's weakening the plant (although one should maybe ask why you feel the need to dose it daily), I do however suspect an accidental 12x overdose may well have kiboshed it.

I'd probably pinch out any decaying/dying leaves and hope the new growth comes back healthy.

P.s your Bristlenose may now well have a taste for echinodorus, even healthy echinodorus, so be sure to feed them some veggies.

You dose EI. From that I deduce that you overestimate the need to "feed them well". I'm not going to support this approach of yours.
What about oxygen?

What do you mean by "feed them well". ?
I dont have a lot of surface movement, 6500l/h pump + 2 maxspects

I mean fertilizing the plants abundantly.

Root tabs?

Plant leaves don't last forever....peel it off!

I trim it every month 😀

 

[G H Nelson]

As long as the plant grows new leaves I don't think you have anything to worry about!

The pleco may have a nibble which damages the Echinodorus plant leaf leading to deterioration and ultimate death of the leaf.
Echinodorus is easily damaged when doing maintenance, something to be wary of.

I think it is time to remove those plecos.

Not saying it's the case here but sometimes people forget that even healthy plants aren't always perfect, leaves die and there will generally be the odd imperfections.

But yes I can attest to Pleco's being a pain having had a mated pair (very tired father) and 300 fry in my tank all at once at one point!

As for Corydora! 😂
