Anubias in trouble - help needed

[Latte]

newbie here
I’ve had my little tropical tank for about 8 months and everything has been doing really well. Recently my anubias plant treated me to a flower but it wasn’t out long (week maybe two) before it seemed to melt and die (not sure how long they normally last?).
Anyway since then it has developed yellow spots on its leaves which are going into holes ?
Could anyone diagnose the problem please and any advice to rectify would be really appreciated . Many thanks

Is it planted past the rhizome (the bumpy things above the roots)?

Thanks for your reply. No - rhizome is carefully glued to lava rock - been this way for 8 months and seemingly very happy until now. No water quality issues.

Do you use fertilizer?

Do you use fertilizer?

No I haven’t used any fertilizer - our water starts off with reasonably high nitrates and I assumed that the additional nitrates produced through the cycling process would be more than enough nutrients. Are my assumptions wrong? ?

I would try a liquid fertilizer like Thrive and see if your plants look better. Plants need more than just nitrates to do well.

I'm no aquatic plant specialist but I do know that my anubias began looking a lot better when I began using fertilizer.

It looks like your tank has pretty good light levels. In my experience, anubias kept in high light needs a healthy level for ferts in the water or else they develop those yellow holes that yours has going on. As mentioned by another poster, just a standard liquid Fert like aquarium co-op's easy green or thrive will most likely do the trick.

Mine also lasted about that long on flowering but tank is not the best (presently pulled down for shifting). Potassium could be short.
